They seem to have multiple different products listed with that title, this one contains nitroethane: https://uk.rs-online.com/web/p/acrylic-adhesives/0144383/

Can it be isolated? DCM is easy but the other not so much, ever work with nitroethane in water?

Most company,s that seam willing to ship reagents are so expensive jeez quoted 190EU for 1L of propionyl chloride ridiculous considering 1L of 99% +
propionic acid is 25EU let alone the MEK route cheaper sources are difficult

In the near future I'd like to obtain some THF (sufficiently pure for running Grignards) and also trimethyl phosphate and dimethyl carbonate
(sufficiently pure for methylation reactions.) They don't need to be ultrapure, just pure enough to reliably run those types of reactions. Does anyone
have suggestions for sources that will sell to amateur/home chemists? I have considered distilling THF from plumbing chemicals, I think it was PVC
piper joiner, but I'm not sure if it would be pure enough for a Grignard.

Check out some of the new online sites in the UK and I suspect elsewhere for vaping and cosmetic chemicals! 1,3-propanediol, triethyl citrate, various
substituted dibenzoyl methanes, pyrazine-methylketone etc.
All sorts of interesting things come up on a google search.

Bumping this.
Just made a purchase from Chemcraft. I have bought via eBay a couple of times and knew they stocked a good range of items. (Really nice element
samples of Na and Be.)
There is a wide range of stock in the store, https://chemcraft.su/ and I was delighted with prices and shipping costs. Very worth checking out.

I just found this site by chance.
I have no Idea, why you would want to eat aminoguanidine, but I will have other uses for it definately 
7,5g for under 25€ is quite OK I think. I paid via invoice, that I can pay Up to 14 days after arrival, because at first the website seemed a bit
sketchy to me, but it came in Just a few days.
https://www.supersmart.com/de--blutzucker-cholesterin--amino...
Besides the Aminoguanidine the only other ingredient ist rice flour. Right now I'm dissolving the Aminoguanidine HCl from 20 Pills, then I will Filter
it and try to precipitate it with NaHCO3. I will let you all know how it turns out and if these pills are indeed legit. If they're not I loose nothing
because I have 14 days to pay the Bill and If the stuff is garbage I Just send them Back

Its a strong-ish base. If it did not bubble off CO2 when you added the NaHCO3 you may have made the bicarbonate or carbonate and not the free base.
I have some metformin the double version of the compound with a couple of methyl groups on one of the end nitrogens.
I am wg48 but not on my usual pc hence the temp handle.

Yes, the bicarbonate was exactly, what I was aiming for, because of its low solubility
Aminoguanidine can be used to make 5-Aminotetrazole, which is a good starting point for various Tetrazole derivatives and that is, what I want to use
it for.
Check this thread for information about various tetrazole:

Tips on Pricing chems
As of now I have not purchased any really "obscure chemicals", but now Im on the look out for ethylene diamine. The prices are outrageous on sites
like fisher sciences. When I was on the hunt for sulfuric acid I found some on https://www.dudadiesel.com/ for 10 bucks a litter. It was 100 dollars for half a litter on fisher and sites like wise! I have no idea how much
ethylene diamine would go for. Need some advice on how you all price items and where to look for deals. Thanks!

Just wanted to post a list of sites I’ve found; some of them are more than likely repeated in the thread earlier. ****** I HAVENT BOUGHT FROM ALL OF
THEM SO I CANNOT VERIFY THEIR VALIDITY****** Also, you must be responsible for any and all restricted reagents bought and your uses for them. I’ve
included where each seller is based and what they mainly sell but I do not know where each seller may ship (into or ntl). Unless specified, the listed
sellers should sell to individuals (may require a statement of usage but that’s no problem) but I doubt many if any at all provide crypto payment.
-Good Luck All

Is there some general beginner guide on here somewhere for how to go about getting basic solvents and reagents in the EU (preferably without breaking
the law)? Seems like DCM is illegal for individuals to possess in my country, and diethyl ether recquires special permission to import as it (and a
bunch of other basic solvents) is viewed as a narcotics precursor. I've looked at different cleaning products, paint stripper etc. but haven't found
any great options. It's very frustrating.

If you buy things from inside EU to be delivered inside EU the shipment will not pass customs even if it crosses country borders.
Now, if the sender declare the content to be anything that isnt allowed the shipment may still be stopped and you could get into trouble.
But if the sender declares the content as "hobby supplys", "Cosmetic supplys" or anything general there should be no problems.
Dont ship with DHL, thay are strict about chemicals and require very much documentation from the sender.
GLS and Schenker are better options.
One of the easiest ways to get chemicals and solvents are to order from one of the members here that do sell these things.
If shipment is inside EU there usually isnt any problems even if content are for example Diethyl Ether, sulfuric acid.
This seller i have had good experience with and never any problems with shipping.

source of Sodium Cyanide?
Hey folks,
I'm looking at making some CN based copper strike plating solutions but, not surprisingly am having trouble find NaCN here in North America.
Any suggestions for sources?
Thanks
