Question Brown methylone crystals (trouble)

[antrax]

I have crystallized the bk-MDMA crystals, then I have recrystallized it with dionized water (to make it purer) and it still has a brown color (I guess due to impurities) and the crystals smell like methylamine, my goal is for the crystals to be transparent in color .

I can answer you. so from what I know, the precursor, i.e. 2b34m, must be clean, then 1 by 2 there must be a very good bath after amination in water and baking soda, water alone does not cleanse the product of methylamine after souring, there cannot be excess acid and the freebase solution cannot be heated, it must be kept in an ice-cold bath all the time. after 4, hcl powder must be pure white, if it has a different color - yellow or brown - there are impurities. If we already have pure fine methylone hcl powder, then we can crystallize it

Minute 0:44, as you can see the color of the 4-MMC crystals is orange, and I do not believe that such a large-scale laboratory synthesizes impure products.

but how do i have pure CAS 52190-28-0?

These same crystals, after a second recrystallization, now look more transparent than before, and lighter brown.

more time u wash with acetone and u can almost pure crystal

After crystallization/recrystallization, how are the crystals washed with acetone and with what quantities? I took a small beaker and added a little acetone and the bk-MDMA crystals and then filtered the acetone from the bk-MDMA crystals with the help of filter paper.

i done it right?

yes
