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 :D
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 ;)

Well I Just added a solution of NaHCO3 to the filtered solution from the pills and after standing in the fridge for Just 5 Minutes it seems like we got something :)

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.

Thank goodness for Fleming and the fungi.

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:

there is a site called wayback aka The Wayback Machine. amazingly, it backs up the entire internet at varying intervals. I had a very interesting hour or so perusing your link at different dates in the past.

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!
