How much did you pay per gram?

I follow this route of chemical synthesis of bk-MDMA: https://bbgate.com/threads/bk-mdma-synthesis-easy-and-fast-method.6423/

Have you ever synthesized bk-MDMA?

Is it more effective to close the container so that the gases from the methylamine 40% aqueous solution do not escape or leave the container open so that the gases escape freely? Thank you!!

How many accounts have you already created in this forum?

Do you know if in the methylamination process of the organic base it is better to cover the beaker so that the methylamine fumes do not escape or leave the lid open so that the fumes escape?

8 hours of stirring? I synthesize bk-MDMA and after the precursor CAS 52190-28-0 is dissolved with DCM and then I add the of methylamine 40% aqueous solution I stir it for 1 hour, then I do the extraction of ethyl acetate, I wash the free base 3 times and then add the 35-38% HCl & acetone...

You may need to recrystallize the 4-MMC HCl to remove impurities and purify the product to make it more potent.

I have synthesized bk-MDMA following the synthesis route shared by the user @Acidosis from the precursor CAS 52190-28-0, after obtaining the HCl of bk-MDMA (a fine white powder that shines) I recrystallized said HCl of bk-MDMA with deionized water and I let it sit for several days in the open...

Look at the color of my last batch of methylone crystals after recrystallizing the methylone HCl with deionized water and letting it sit for several days in the open air with a transparent plastic tupperware.

Could you give me the contact of said Spanish P2NP CHEMICAL supplier?

Did you finally synthesize amphetamine sulfate (speed) following this route?

Nice crystalls, Do you synthesize MDMA from MDP2P starting with PMK glycidate?

To measure pH do you use pH measuring strips or a digital pH measuring device? For filtration, do you do it by gravity or by vacuum? To separate two liquids of different density, do you use a separatory funnel? During the methylamination process, did you close the container so that the fumes do...

is the methylamination with methylamine 40% aqueous solution of the precursor CAS 52190-28-0.

the yield of said 4-MMC chemical synthesis route, with 30-45% do you mean the yield of mephedrone crystals after recrystalization? Thank you!!

Too low yield, Maybe the pH was not 6, the methylamination was not carried out correctly, you lost product in the filtration, the precursor was not pure enough, or the reagents were not of good quality, there are many hypotheses. Thank you!!

I have doubts to know if during the methylamination process it is more effective to close the container so that the fumes do not escape or to leave the container open. Thank you all!! ;)

Thank you all!! ;)

Hi! my friend, How do you get transparent crystals after recrystallization? I have synthesized methylone but after recrystallization I obtain orange-brown crystals and that I think means that the methylone crystals have impurities. Thank you!!
