Do you mean it is available without prescription by the vet in some countries?

Hi, I was surprised to see all these negative comments, mentioning everything except the answer for the question. Now, I don`t know what is available/unavailable in the questioner`s country, but this forum is to help each other overcome difficulties and I am sure there are solutions to almost...

Company formation is actually not a bad idea at all. If the company`s profile is such that certain chemicals, H2, lab equipment etc are normal for such a company, then I don`t think anyone will look into the age or the annual revenue of the company. And even if they do, it can be a startup...

I have just recently started to look into precious metal catalyst, as they are much more efficient if done properly. The problem is that I haven`t found any good guidance on this, even youtube has only a couple of videos. Can anyone recommend some good educational material? PM or comment here...

O, O ′-dibenzoyl- (2 R ,3 R )-tartaric acid CAS: 62708-56-9 https://www.erowid.org/archive/rhodium/chemistry/meth.resolution.di-bz-tartrate.html

Xiao hua, most of the phenylethylamines can be separated this way, although it is quite labour intensive to achieve relative purity of the D isomere. I recommend you look into DBTA. It is supposed to give a high purity after only one crystallization and the original patent uses methamphetamine...

Sorry to say, but I don`t think this would work for several reasons. Hg does not facilitate the reduction by stripping the Aluminium oxide off (although it does destroy the coating in the process once it came in contact with the aluminium even at the tiniest spot). The reduction happens because...

I double what Hank said about colour, it took me quite some time to arrive at a relatively pure Amphetamine distilling the oil twice, and the colour is white/transparent. I can`t even find any yellow in it. For distilling oils short path is great, before this I used an air-cooler, as room...

Lordoftheshard, the optical purity for pseudo/ephedrine derived meth is 100% D-meth (ephedrine and pseudoephedrine are isomers of each other. The molecule has got 2 stereocenters and ephedrine and pseudoephedrine differ in one of the stereocenters, the other one is the same, and this latter one...

Both ephedrine and pseudoephedrine gives D-meth as a product, there is no difference, they are equally good.

I had a long period of trying to get Acetone-Sulphuric acid mixture for salting, and the only way to prevent the formation of mesilates (red colour and awful smell) was to use freezer cold acetone and acid, but even with the utmost care it would turn red after a while (couple of hours). My...

Why don`t you run a TLC for the two products (pseudo & NaBH4 - meth)? If it is the same molecule then perhaps the resolution is not right. Pseudo gives 100% D-meth, from P2P it is difficult to get close to that purity (and impossible to reach it). It would be great to get to the bottom of this...

Thank you Patton. I don`t have any suspicion that my nitroethane is not pure, but having read some comments, I thought it would be better to check, so I will start with the boiling point of my nitro and if it boils over 110C then I will rest assured. It is good to know what to do and check...

That would be so cool, especially if explanations/advice is added to each step (e.g. what to look out for, how to prepare each material etc.). I would contribute to buying such video, Heisenberg, let me know if the deal is going ahead.

T0R, the link does not work any more, can you please share this video again?

Patton, I have all the ingredients to do the Bromoethane-NaNO2 route, but would like to scale up to at least 10X the amount in the description - to have about 200ml of Nitroethane in the end. This would however require ridiculous amounts of solvents e.g. 6l of DMSO/DMF, then huge glassware when...

What is the best way to check whether the nitroethane I used to make p2np has been replaced or diluted with nitromethane? I have collected the basic physical properties of both reagents and products and to me the boiling point of the nitro compound seems the most logical. Melting points of the...

Patton, can 1,2 Dichloroethane be substituted with something else? This solvent is quite difficult to get, I have searched and couldn`t find it anywhere.

Based on my results with sulphuric acid drain cleaner (instead of phosphoric acid which I didn`t have at the time), this is what I got in the receiving flask after the steam distillation. I figured this can only be P2P+water, the P2P separating as a separate layer in the distillate.

Is it useful to wash the extract with distilled water to get rid of anz possible Hg salt at this point, before drying or is it unnecessary due to the distillation in the next step?
