Methanol - tech grade - 12 quarts for ~$40USD
pricing:
1 qt(liter) - $1.56 USD
4 qt = $6.24 USD
12 qt = $18.72 USD
You get the idea. Shipping was $20 regardless of how much I ordered(unless it was a freight amount)
The company clearly exhibits business integrity. They offer to create an account (standard procedure for email marketing), but make a point to tell
you that it is NOT required.
They use PayPal as their online POS, but also take a moment to inform you that you can just scroll down and choose "use debit/credit instead" so you
won't have to make a PP account.
Some other pure chemicals they offer:
Propylene Oxide
Nitromethane(requires statement of intent form)
But across the board the pricing clearly is derived from what THEY pay, not how much they can get.
This company has been mentioned on this site before, just wanted to update that they still exist and are still shipping(USA based)

Just bought it because it's a useful compound. First will make some 4-bromoanisole probably simply with elemtental bromine.
If you use the search function here with "anisole", you will find a lot of ideas.

Yes Schleimsäure, plenty of results when using search function, but nobody here did any experiment with anisole. I've bought it to know its scent and
for me it is not pleasant. Far far faraway from anise. I have natural anise essential oil which has pleasant scent for me.
https://fichema.cz/anyzova-silice/1618-anyzova-silice-10-ml-...
https://fichema.cz/index.php?controller=attachment&id_at...
But the scent of the anise essential oil is due to trans-anethol, not anisole. A lot of anisole derivates have better scent than the anisole itself,
but it seems easier to obtain them from natural sources rather than home lab synthesis from anisole.
I'm afraid my anisole stays only as a sample of its scent in the original bottle instead of any useful experiment/synthesis.
Please post your synthesis of 4-bromoanisole when you perform it. Do you plane some Grignard reaction with it?

My first Purchase from an actual lab supply company in Canada
500ml of glacial Acetic acid and a 100ml burret tube + Clamp!
Will be ordering metal powders next, Zinc, Iron, Magnesium and some clamps
https://www.westlab.com
I ordered from them, no hassles no litany of questions!
For Canadian Buyers I'd recommend them

I ordered three chemicals
1,3 butanediol
1,4 butanediol (stupid mistake, hopefully will be corrected)
sodium ethyl sulfate
I found it quite interesting to see two isomers of butanediol and explore the differences. I expect that the 1,4 butanediol can be used to make a
dialdehyde, with two aldehyde groups at each end of the molecule. Such compounds have quite interesting properties, both for polymerization
experiments and for coordination chemistry.
Unfortunately, I also found out that 1,4 butanediol is used as an alternative to GHB and GBL as (dangerous) recreational drug. I did not know that
when I ordered the three chemicals. The seller told me the stuff will be shipped at the end of the week, so I partially canceled the order and only
left the 1,3 butanediol and sodium ethyl sulfate in the order. Hopefully the seller accepts the change of order. I personally do not want any straight
out drug in my home lab. Some possible precursors like red P, acetic anhydride are a different matter, but stuff which can simply be ingested as a
drug will not find a place in my lab.
Supid mistake, but I think that it can be corrected. Enough interesting things remain to be done with the other two chemicals.
I posted this, just to let you know how easily one can order a drug even if you do not intend having any drugs around.

Catalytic dehydration of 1,4-butanediol affords THF. You could probably make use of it. Otherwise, I'm sure somebody here would be willing to take it
off your hands.

This is probably not the right place for it but I thought I'd mention I saw moth killer at the hardware store claiming to be 99 percent
p-dichlorobenzene.

I think that's standard for moth balls and urinal cakes in the United States. The trick is to find naphthalene, which has been phased out from these
uses in the United States. I saw them once at an international store, and they are still available online.
But to contribute on topic, I am finishing a purchase of isobutanol, sec-butanol, ethyl benzene and pyridine from SM user Chemglass. So far so good.

Thanks, and seconded. I just received 500ml of conc. sulphuric from them. Absolutely hassle-free and CAD15 for shipping (which was done right, too, ie
properly packaged and shipped as hazmat). Pro-tip for any Canucks following this recommendation: If you're in an area where courier deliveries are
depot pick-up only, maybe ask in the notes that they put your phone# on the shipping label, as it seems they don't do that by default.

I finally knuckled under and purchased some potassium perchlorate from skylighter. I wanted some for metal salts, not energetic endeavors. But every
time I went to select some, I just couldn't bring myself to click yes... The price per pound too high after shipping in small quantities. But they
put it on sale for less than the chunky (discount ) price stuff that's been sold out for a while now... And 10#'s was $52. 77$ with shipping/tax.
Not bad delivered. One lb alone was like 11$ before tax/shipping.
Always too much product to get an acceptable price. What ya going to do.

I've read old papers at some point with heavy metal salts on electrochem, probably electrodeposition of metals. More specifically Ni though I want to
try Co, Cr and maybe Pb, U and Th. Hopefully it will be more useful than you think for me. I do have propylene carbonate, not to mention PLENTY of
time before I'll use it.
Plenty of time to read. Lab's still packed up, prob won't change untill I buy a home.

What metal salts will you make with KClO4? KClO4 is insoluble, so I don't think that you will find it useful for this purpose.

KClO4 is soluble to water at higher temperatures.

Using KClO4 for making other perchlorates or perchlorate complexes is hardly possible. KClO4 indeed is soluble in hot water, but its solubility in any
case is much lower than the solubility of other perchlorates. I know of only two exceptions. CsClO4 and [Ni(NH3)6]ClO4 are less soluble than KClO4,
but even with these, getting them in a pure state from KClO4 will be hard.
You'd better get some NaClO4 or HClO4 for your experiments. I almost exclusively use HClO4 for experiments with perchlorate salts. I also would like
to use NaClO4, but that's not possible in the EU. I sometimes use NH4ClO4 (which is allowed here), but NH4ClO4 also belongs to the somewhat less
soluble perchlorates, so it certainly is not my favorite perchlorate to work with in experiments on metal complexes.
So, if you are in the US, get yourself some NaClO4 and use that for interesting experiments on metal complexes. If you are in the EU, then the only
good alternative is (expensive) HClO4.

I bought:
two jar of BeO (in hand)
MoO3 (biggest, with glass lid))
Ampoules of many chemicals
Palladium chloride
CO detector from 1958 (small white ampoule with black stripes)
Gas analysators for chemical weapons analyser divice (which i don't have)
Thorium nitrate
All other reagents are for analytical chemistry all of them are soviet and
czechoslovakian reagents.
I also buy benzidine, sulfanilic acid, fenamic acid, thymol, disodium EDTA and many similar reagents.

Very rare here, I have a few ampoules that are from a Soviet military base. I think it was for some military device, which i don't know like everyone
I asked.

What experiments are you going to do with thorium nitrate? I don't know much of thorium chemistry, I expect it to be a fairly inert species in
oxidation state +4, which cannot easily be oxidized, nor reduced, to another oxidation state. I know it is only very weakly radioactive (appr. 1/3 of
completely depleted uranium). I do not expect much colorful chemistry of thorium, so I am looking forward to see results of your experiments with it
here on sciencemadness.

In ampoules there is oily liquid. I think this is historical sample and maybe i won't use them, also ampoules don't contain much thorium they're for
device, not as a reagent, i think i will start thorium chemistry when i will found solid salts. Also i dont know which isotope it is, maybe 232, but
I'm not sure, unfortunately I don't have geiger counter. You are right i agree with you, almost all compounds are white, exept chromate and you know
similar anions.
