I know this doesn't matter to/doesn't affect a lot of people here, but recently the DEA added a bunch of chemicals to their "special surveillance list" Now I know this doesn't stop packages from being mislabeled, but it does add on less layer of legal protection for the home chemist if the...

Ok, thank you so much, it makes sense. Asking because I saw a video about some small scale mdma chemists, and they used a 5 gallon bucket as a reaction vessel, and then extracted the MDMA freebase with xylene, all in the 5 gallon bucket. I though xyxlen is incompatible with hdpe plastic, but...

Alright guys, this is an easy one. I know methylene chloride is usually preferred, but can ethyl acetate be used to extract MDMA freebase? Same I guess with MDP2P? I know there are better solvents, but I am just wondering if it is still a decent option.

Would you be so kind as to dm me about some of said drugs? Thank you

the Only way it Would make sense is if one could attach the amine group AND the protection group at the same time, technically avoiding making the illegal drug at any point. But that seems unlikely.

Absolutely, the ”standard” ways of drug distribution are the standard for a reason. The only way this would make sense is if someone was trying to sell them in countries with analogue laws, or trying to have a shred of legal hope for say transporting person use amounts across borders.

Any reason, besides increased cost, this reagent can't replace regular sodium borohydride? Besides being incompatible with methanol, it seems a good substitute for regular borohydride for all amphetamine related uses.

In the US, are there any options to get say hplc and other testing done while being anonymous? Can one use testing service out of country? Would like to get a sample tested for purity percentage, but also want to be safe.

I'm not sure how true that is, from a surface glance it sounds completely false. First, people have been smoking heroin off of foil for decades...they are not dropping dead from ketene poisoning....and that has two acetyl groups, twice the ketene, according to you. Lighters burn at roughly...

This article got my attention and curiosity. https://pubmed.ncbi.nlm.nih.gov/27574107/ Apparently, in 2015, authorities seized tert butoxy Carbonyl mdma, which is just mdma with protecting group stuck on the amine. I think this might be a great way forward toward drug smuggling, and...

Pretty sure for mdma shulgin found that both enantiomers are required for the "full" effects. I don't think separating the enantioners is worth it for mdma

Made in china has some real things, I would just not use new companies

No offense, but I'm not seeing where it mentions meth, secondary amine (besides someone asking my same question). Are you sure this is the right thread? Seems like someone basically just asked the same question I did.

Over many forums, including this one, the leuckart is a well know way to reduce ketones to amines. However, for our favorite substrates, it seems to be a poor fit In several ways. First, the yield, it seems to hover around 40% or so, and that lesaves much to be desired. we need to improve it...

I've read how cartels will ship base methamphetamine from mexico, then convert it to the hydrochloride in the US. I was wondering if anyone could answer why they do that, but also why isn't this done with cocaine? Perhaps too valuable per gram, perhaps too much trouble? I assume however they...

Can urushibara catalysts produce mdma or meth, and which variety of catalyst if so?

Is this even possible? Under the hydrogenation link posted here, it says it is not, however I find parr shakers don't come in big sizes that the big dogs in the Netherlands require. They put out hundreds of kilos a day, and parr shakers, as far as I know, are just not going to do that. Despite...

So if the purpose is to neutralize the acid, why wouldn't a sodium hydroxide solution be able to replace the bicarbonate solution, assuming they are the same ph? I just don't understand why such a large amount of bicarbonate solution has to be used.

Can one replace the bicarbonate solution with a lesser amount of a hydroxide solution, assuming they are the same ph?

Patton, are some of the batch reactors listed here good for using precious metal catalysts? I know parr reactors are commonly used for pressure reactions, but I am wondering if these will do.
