@Acidosis Muito obrigado por contribuir com a sua síntese para o fórum. Vou experimentá-la, sem dúvida. Escreve que "o precursor é muito, muito barato". Posso perguntar quanto paga por 1kg e, caso não haja conflito de privacidade, pode dizer-nos quem é o seu fornecedor? Obrigado

Há vários vendedores no alibaba que oferecem o precursor, mas não é barato, a não ser que não saiba o que significa "barato" para si, já me ofereceram a substância por mais de 150 euros por kg.
Isso é só o precursor, os reagentes químicos utilizados na síntese também custam dinheiro.

380USD with shipping. No tax, or additional fees.

No, I'm not sharing. Not to be a dick. It's because I know how red flags, logarithms and algorithms work. CYA. Cover Your Ass.

It's always "buyer beware", and for a few different reasons.

Scammers, police, customs, loss/breakage, customs/police, loss, delivery "issues", junkies stealing deliveries off the front porch (which is how they can afford your product), using the wrong carrier resulting in 1) loss 2) your package being opened 3) a search warrent resulting in an especially well groomed "delivery person" performing a controlled delivery that results in you eating shitty food in a small concrete room for the next 3-5 yrs or more. Dickheads. "Sneaking and peaking". Peace officer? No one sneaking around spying on others personal business is trying to keep the peace. Now I'm in a pissy mood.

It's pronounced "es-press-o".

Tenho algumas dúvidas sobre a síntese química do BK-MDMA.
Que percentagem deve ter o diclorometano, a metilamina, o acetato de etilo, o sulfato de magnésio, o cloridrato de metilona e a acetona?
Obrigado!!!

Acabei de receber 1 kg do precursor (CAS: 52190-28-0) 2-Bromo-3′,4′-(methylenedioxy)propiophenone de um fornecedor chinês.
Paguei 280 dólares por 1kg com portes incluídos, a partir de 25kg pagarei 200 dólares por kg com portes incluídos, é um precursor caro, a pureza é de 99%, a cor é castanha e o formato são pequenas pedras e pó.
tem um cheiro forte (não sei exatamente o quê mas não é um cheiro mau) o formato também se assemelha a açúcar mascavado.

Do you have an address where you can find good precursors? Thanks in advance

Acho que encontrei o problema, a base não se mistura com o HCL, uso HCL 33%, podem ajudar-me por favor?

O Hcl deve ser bem agitado para se misturar com a base livre e formar o cloridrato.

O Hcl deve ser completamente agitado para se poder misturar com a base livre e formar o cloridrato.

O facto de não ter colocado MGSO4 pode ser a causa?

É possível substituir o DCM (diclorometano) por tolueno DCM?

Sim, apenas a base livre está na camada superior, não vá para a camada inferior neste momento...

I read in the comments that it was possible to replace DCM with IPA. Can you tell me if it is in equivalent quantity? Otherwise, what quantity of IPA is required for this synthesis? Thank you for your answers

Could be not enough base was added to liberate the all of the methylamine base from the Hcl salt.

Don't ever add Hydrochloride Acid to DCM to to crystallize. I don't care who said what, or who's banging your mom--- it does a shit job as a crystallization solvent when using Hydrochloric Acid. Dry Hydrogen Chloride *gas is a different story, though. But most don't have access to dry Hydrogen Chloride gas.

Yes, you could distill off the DCM (atmospheric or otherwise), but while it does has a lovely smell, it's a carcinogen. You could try a dilute acid extraction from the DCM, and take it from there, or skip DCM altogether.

You got options.
