you are quite brave when offering here mephedrone precursor, such amounts, and even home made...

10% Pd/C costed me 10000 CZK = 400 EUR / 100 g that is 4 EUR / 1 g that is more than 4x cheaper than your, I already did successfully 1 hydrogenation reaction of double bond, 1 dehydrogenation reaction into aromatic compound, so I can guarantee its activity, the seller offers it in an auction server, so I contacted him and bought it cheaper directly from him (without fees for the auction server) https://aukro.cz/katalyzator-10-pd-na-c-100-g-7017558480
Sm 99,9% (so somewhat less purity than your) costed me 150 EUR / 1 kg which is again more than 4x cheaper than your, I've bought it more than 1 year ago, the seller has it still in stock: https://onyxmet.pl/index.php?route=product/product&path=...

@OrganicGuy: It is somewhat hard for me to assess whether some of your organic chemicals are straight drug-precursors, or not. But if this indeed is the case, then I will have to remove this offer from sciencemadness. We do not want this to be a place for trade in precursors for illegal drugs! So, please explain to me. If others, who are more into organic chemistry, or even into pharmaceuticals, can enlighten me, then that would be helpful also.

I welcome people, who can offer interesting reagents for home scientists, and as we all know, there are a few people, who do so succesfully and who have many interesting things for the science enthusiasts. If your offer also finds a place in (legit) organic home chemistry, then that is fine to me.

Shall everyone here be judged by everyone's morals, then we would have a big time problem in this forum. I suggest you mind your own business if you're not interested buying anything, all I offer here is fully legal where I am at and I won't ship to any country where it's illegal to be in possesion of the substance ordered. I follow the law, and i don't care at all about the moral of people I don't even know who they are (like you for example)

I get how 4-methylpropiophenone would be a good precursor for mephedrone, but how does the 2-bromo help?

Dr.Bob - 27-12-2022 at 17:28

The 4'-methyl is on the aromatic ring, but the 2-bromo is on the side chain. One step to mephedrone. Likely a controlled or watched compound, but not sure myself. Might take a lot of explaining if found in your lab.

He stated correctly that everything he offers is legal in the EU, this includes the bromopropiophenone after my best of knowledge. And sure this is the direct precursor to mephedrone but methylamine is far from being the only possible Substituent so what? Plenty of other options too. And its really common, not long ago it was sold on Amazon by S3. As maybe drug precursor I find this twisted brother of 4-MAR far more intriguing to be honest....

People must know the laws of the country they dwell in, sellers cannot be expected to do this for everybody. And anyways, it is not 25 kg drums he offers together with "special line shipment" and it is just one of many items, not to talk about overpriced.

Besides the prices being a bit steep, I personally prefer to deal with people with a more relaxed attitude when buying chems, actually my favorite fully legal chem shops, namely S3 and labdiscounter are much more relaxed then Organic Guy....

@Fery: Thanks for the Pd/C 10% link, thats something I was interested in for quite some time now.

Organicum, you are in EU, I can buy some for you or share from which I have. I can give you email to the seller, but he sells only in my country, not abroad. Nobody was interested in the auction, he did not sell anything that way. So after the auction I contacted him directly. You can save some money that way, the seller does not have to pay fees for the auction server so the price is lower. I've bought from him various reagents maybe more than 50 times already. I tested the catalyst activity already twice with success. He offered me initially small sample to test but I refused and bought it directly.

Sodium cyanoborohydride aquirement?

Kevlar - 5-2-2024 at 03:28

Hi, for the first time ever.

I'm stuck in the Uk struggling to get NaBh3Cn, I can buy NaBh4 from a few places in UK no problem. But need the more selective cyanohydride for the synthesis I want to do.

Just want to say how much I love this forum!

Kevlar - 8-2-2024 at 06:40

Never mind I've managed to aquire this from China, 100g for $131 Inc the shipping.
