Elemental phosphorus (and all hypophosphorous compounds) are now controlled substances. Phosphorus halides are fair game though.

"On October 17, 2001, DEA published a Final Rulemaking (66 FR 52670) in which DEA added red phosphorus, white phosphorus (also known as yellow phosphorus) and hypophosphorous acid (and its salts) as List I chemicals."

Some phosphorus can't be shipped via FedEx or UPS (e.g., Phosphorus trichloride). I'd have to take a closer look at some of the others. Also, I'm not sure I can find a supplier for Phosphorus Tetroxide. How much of a demand for these?

Oxalyl chloride is best refrigerated. but does fine at room temp for a long time. I would not try to ship it cold. I would double bag it and ship in a metal can, but you likely have the shipping guides. Some of the amounts that you list are pretty large, like 500 ml thionyl chloride. I do chemistry for a living and have not used 500 ml of it in 10 years time. So it might be nice to have a smaller option, as that is an example of a chemical that will be hard to dispose of if you have too much. Same for 1 kg of AlCl3, it will absorb a lot of water before you can use that much of it. But it sounds like a great effort to help home chemists.


Thanks for the feedback. Unfortunately, I found that quantity selection is more limited in these chemicals. At this point, I prefer not to repackage into smaller quantities, so I'm kind of stuck with the quantities offered. Maybe I'll find some additional options in the future.

Tom,

How will some of the items (e.g. Oxalyl Chloride & Thionyl Chloride) be packaged? I would hope that these would be glass ampules, but I do not know what facilities you might have to do that type of packaging. Any help would be appreciated!



I expect glass bottles, but some of these are new chemicals for me, as well. I noticed the Oxalyl requires "refrigeration".


A few of these items I would most likely repackage using safety coated glass bottles, such as those available from Qorpak, if they didn't already come in something similar. I am not interested in glass breakage, especially with things such as thionyl chloride. No thank you.


I don't think we should expect tomholm to provide packaging that is above and beyond that in which these compounds are normally supplied. I have used thionyl chloride in a college OChem lab. It was in an ordinary looking brown glass bottle as received from the school's supplier.

I do agree wholeheartedly with the comments of Dr Bob about needing containers that are smaller, however.

Magpie, I meant that I, myself, would repackage these items into more suitable containers. :)

After rereading my statement, it can certainly be taken in a couple of different ways. I do not expect, nor would I ask, for Tom to go above and beyond what he is already doing for us. I am very grateful.

http://www.deadiversion.usdoj.gov/fed_regs/rules/2003/fr0624...


Phenylacetic acid is List 1, along with Phosphorus and Hypophosphorous acid salts, and yet I seem to recall that it is used by the perfume industry. Thionyl Chloride is on the Special Surveillance list, along with 22 liter heating mantles lol (wikipedia). I recall seeing someone just recently selling "amorphous" phosphorus on eBay in small amounts.

It was my assumption, and it is not like I have spent any considerable amount of time researching this, that Listed was very different from Scheduled, and that Listed implied their intentional usage as part of a clandestine synthesis was illegal, and that only tighter auditing controls were placed on them.

I need to do some more research on this, however, as everything I have stated above is purely my opinion.

tom,
is there a possibility that you can buy certain things in larger quantities, repackage them and sell like that?
in larger quantities things are a lot cheaper so you would make more profit and provide lower prices,

heres an example from aldrich for benzene.
156302-250ML 12.80

156302-2.5L 49.00

156302-25L 245.00

I'm pretty confident i could ell it for more than 20EUR/l, in fact if I had a company I would order it today.


PCl5 should be less of a problem for shipping as its solid

Because most of these requested chemicals are pretty hazardous and I don't have any idea of demand, I am not prepared to handle and re-package these chemicals. Perhaps it will make sense in the future, but for now, I don't intend to sell them in the quantities that I can purchase them.

Thionyl chloride is restricted under the chemical weapons convention. You will need an end user declaration to purchase it, but other than that it should be fine. Phosphorus and phosphorus chlorides come under the same scheduling, too.

The American chemistry businesses have been taken over by lawyers. I suppose the root problem is DEA letters and phone calls exceeding their authority but fearfulness and lack of spunk in the industry is ultimately to blame. Fortunately the Chinese new capitalism has stepped in to fill some of the voids. Some of the better ones will work through paypal. Others will use escrow services. It's more work for sure. You may have to post your desires on a web site such as alibaba. From there you will get offers to purchase metric tons or tonnes of HaOH or whatever. Then your work begins. You have to make contacts with what seem to be likely prospects. Eventually, through persistence and a bit of intuition you will find you can purchase fine chemicals and weird salts. Don't discount the homegrown specialty market. In pure frustration with the lawyers I started making piperidones for self and a few others who are willing and able to pay the price. For some of these the devil is in the intermediates. It all makes me think I should start a chem company..but no, you have to maintain stocks. Try to find a lawyer-free environment. Help Shakespeare...the bastards ruin everything!

Hi DJF90. Would you happen to know if that requirement applies even to small quantities, ie, is there a size (ml or g) cut-off point?

Just go to the web site, www.elementalscientific.net. Click on the "Special Order Chemicals" category to see the chemicals available. Complete the purchase the same way you would any other purchase. You can also add other, non-special order items to your order.

Just remember, your order will not be processed until after the special order date listed.

There's plenty of subtle misinformation here. I'm sure I'll miss something because I only skimmed the thread.

Why are some chemicals becoming hard to find? Partly because nobody uses them anymore. The east coast research lab where I worked in the late 1990s is gone. Work outsourced to another country. Academic labs still do what they do, but I suspect more and more chemical research is theoretical instead of bench top. Some people have implied on other threads here that if they had a contact in an academic lab stuff would be easy to get: maybe in some places it used to be that way, but not at most anymore. A friend getting a PhD at Berkeley told me that in his building at least, everything ordered from Sigma gets several eyes on it and there's absolutely no way he could get something unrelated to his research. I wanted something profoundly innocuous compared to what people are talking about here. OH BTW, a hobbyist chemical buying club...even if it had a business location and corporate entity...even if it had a Chem. Degreed "sponsor" would be laughed out of town by the major lab suppliers like Sigma, Fisher, Spectrum, et al. Maybe one of the 2nd degree resellers would at least talk to you. The fact is I've been interested in ordering hobbyist chemicals since I was in college in the mid 1990s, and many, many suppliers have come & gone. It just isn't a very profitable undertaking...or the risks undermine the profit severely.

Hazardous can certainly be shipped by USPS under exemption. I've gotten NaClO3 from fireworks suppliers that way. (Anyone from the EPA reading this forum has already had a stroke by now, so I'll just admit I was curious to try it as a weed killer. I have several acres and battling weeds is a constant annoyance. It used to be very popular in Europe. Turns out it kinda stinks, at least with our American weeds haha. I'll stick with roundup. It was fun to do the gummi destruction experiment. I got most of my "blowing stuff up" urges out of my system in HS & college. I might have related how we did the thermite reaction freshman year, and an old timer campus cop came along and said "what are you kids doing"...I think I was the only one who had a twinge of anxiety as I was probably the only one who was sober. He accepted our explanation that we were just doing an experiment - that was in the halcyon and innocent early 1990s. These days we would all have spent the weekend in jail and been expelled. We used our own supplies, not stolen from the chem. department although a couple of us were chem majors.) It's just that many sellers, and certainly the big lab suppliers, have no reason to hassle with it. If you're a university chem. department in the US, you have enough money with the tuition you're charging to pay hazmat fees. AND...some sellers (not the one on the thread, I guess) will say Fedex refuses to ship Hazmat to residences. Again, untrue. I've had FCC/USP grade HCl delivered to my house from a reseller. I had to sign for it of course, and the Fedex guy gave me a "what the hell are you doing with it" look. But - knock on wood - no DEA agents have come knocking at my door, at that was back around 2011. Which is so utterly stupid because anyone making drugs would just buy it at Home Depot...almost as concentrated. At the time I was experimenting with creating a shelf-stable predigested protein product. Acid digestion turns out to be a complete waste of effort. The right enzymes can digest almost anything to completion w/o pH modification.

DEA list chemicals are certainly not "controlled" in the same way hard drugs are. I once found a flavoring company perfectly willing to ship me a large amount (500g) of piperonal. But I didn't, because the DEA audits all such purchases and will certainly feel obligated to check out why you ordered a list I chemical. And make life difficult for you even if you do really want it for flavoring. SOME suppliers, like the major lab suppliers, now prefer to check that you have a DEA license before selling you a list I chem, but they are not obligated to do so. (and yes, at the time I was experimenting with flavorings and thinking of starting a flavoring company. As it turns out, nobody messes with the actual chemicals themselves anymore, except maybe McCormick. If you want to start a retail flavoring company these days, you just open an account with Givaudon or Bell...and I did with one of them...and tell them what flavors you want to market. They will send you a mix you can dissolve yourself with dilute EtOH...once you get over the hurdle of a TTB repacking license. But I could never get myself into the marketing, which is what it's all about anyhow these days. People buy for cute labels and slick websites, not for caring whether the ingredients are high quality or not.)

While I'm discussing this and I am still beset with insomnia...
there is the slightest, tiniest ray of hope in this era of insanity. (beside the helpful poster here who is willing to help people obtain the things already mentioned; I wouldn't want them in my neighborhood much less in my home, but it's a free country, darnit)

I notice Pharmco is letting Science Company in Denver sell a handful of their more innocuous solvents, on the Sci. Co. website, under their label. I was completely shocked. I guess they finally realized, geez, people are buying our stuff on ebay anyhow, why be so anal about it? I think for every ray of good news in the amateur chem. supply newsfront, there are 10 bad ones. So don't get too excited. :(

Um, yeah, that's sort of exactly what we're already doing... We're talking to Elemental Scientific and they're being really nice and doing everything they can to supply us with what we need. That was kind of the point of the majority of this thread.

"That was kind of the point of the majority of this thread. "

Well, somewhere else someone had acted like the primary lab suppliers would be cool with it. They would not.
It's <b>great</b> news elemental is helping you - believe me I have no objection to it - but I would call them a 2nd or 3rd tier supplier. Not that it really matters. As you can see I complemented them in my post that came a split second before yours. As I've posted before, if someone can get me SAFC (Sigma's food line) ingredients, under their label, do privately message me. Although I've kind of moved on from what I was doing a couple years ago. I just came here tonight because I was bored!

I believe that was in Pyro's post. He lives in Europe where for some reason(s) those primaries like Sigma and Fluka will sell to individuals (some countries). Maybe it's because they don't have the DEA lurking over their shoulder, or the citizenry is not so litigious.

I'm glad to see the special order chemicals are live on the website :)

Once again, is it OK to ship to Canada? I see two options, Hazmat packaging and Hazmat packaging/shipping. The packaging only one sounds like normal shipping with the special metal can inside.

Yes, we can ship most items to Canada. Pretty much the same shipping guidelines.

You are correct on shipping charges. Hazmat packaging/"Poison Pack" has the extra can/layers of packaging that allows it to be shipped without the hazardous shipping charges (under an exemption). Cost is $17.50.

Hazardous packaging/shipping is the hazardous shipping charge. This too, often requires the additional packaging. Cost is $30.00.

We will try to combine as much as possible to save on charges. Unfortunately, very difficult to provide exact pricing until the entire order is analyzed.

Thanks.

I did some research to see what requirements apply to Chemical Weapons Convention schedule 3 chemicals in the US. The only requirements I could find are shown here:

http://cfr.regstoday.com/15cfr714.aspx

Unless I have missed something it seems that the requirements apply only to manufacturers and import/export companies. And the cutoff-point is 30 tonnes!

Does anyone else know of any CWC requirements that would apply to Elemental Scientific or the US home chemist?
