Pre-ban Cathinones. Unable to replicate. [bounty!]

[Morda]

Well to what has been known, Dragon Eric(yes the one who “turned scammer later” /long story apparently accounts were taken over bla bla bla…) and other major China supplier, never did supply pure 4mmc it was a mixture.

I remember reading a post on different hive, where Eric apparently accidentally (or intentionally) shared some informations which were swiftly deleted. Stating proportions of 70/20/10 and 80/20. Since then it was just an ongoing debate regarding this subject. I can’t remember out of my head what was it exactly. I can try searching for the old conversation if that’s going to help anyone.

if anyone remembers they used to sell verity’s of Eric1 Eric2 Eric3 “same” but slightly different.

also apparently “Eric formula” was posted on sale at very steep price few years back not sure if it was real or just another scammer.

i have also seen someone say that 4mmc from china wasn't pure, alegedly it was mixed with 3mmc, however i have no source to support that.

but it would check out if now nothing can beat chinese mephedrone, i'm no chemist but what is so different now than before?

you can make a super high quality product now just like you could before, i guess

Oldcool 4MMC is mixture of 3/4MMC but actually i find people preffer 3MMC because people want more of stimulation feel than the speedy calm effects of pure meph, also i see some people look for teacher im an ex chemist with lots of experience if anyone is intrested can PM me

 

[mefistofeles]

i have also seen this info somewhere but isn't the 3mmc the more speedy one? 4mmc has a lot more stimulation while not being speedy

3mmc is more like meth while 4mmc is more like mdma

3-mmc is cleaning up your house with a smile and horny as fuck

I submitted a sample of some recent self-made mephedrone to the lab and it came out 93%, which suggests higher purity than the commercial preban sample .

So now I'm even more confused since this tastes so soft, no throat hit, effects are less. I would, without hesitation, trade in 1 kg for 250g (yes, that much of a difference)

While really, one would think a molecule == molecule.

I almost starting to think the much sought-after effects might be due to impurities or byproducts now THAT would be a paradox

 

[Jantje]

Did they differentiate the actuall mephedrone from it’s isomer ? I got the feeling they be adding them up as the same product..

 

[TheVacuumGuy]

Yes, what i sent first time was 3-mmc, and this time sent 4-mmc. They differentiate very well.

Western world uses DCM like solvents which have very low water solubility. The Chinese did not use any of the solvents mentioned on this or any other site. I have come across some startling new information and might try that offbeat easy synthesis thia weekend nd will report back. Q good synthesis i believe will perhaps reduce purity, have low yield but would under circumstances normally it would not easily cause a failed batch resulting in waste of efforts money and chemicals .
Of this is half as promising as it sounds. Might be on to some chinaman strength meph.
DCM etc r ok but very low yield if batch is big.. like my last 12 kg batch ruined by adding NMP to speed up the process based on herrbarr s improved sunth using dcm. If your 2b4m is very pure it might work but with some unwanted particles in the 2bromo,4 m, nmp is always a bad idea.
The trick might be to use a catalyst that embraces all the ma40 and makes sure maximum conversion of the bk occurs. The polar solvents only react with the methylamine at the layer of contact since the solvents are not very friendly with water. I gonna try this magic new recipe. Ttu guys later
..BOOM

Interesting. I've heard before someone adding some nmp to "speed up" the process.
However, the process is also very much sped up by using a mechanical stirrer. Takes me 35 minutes until the temperature goes down and the reaction complete.

let me know whenever you get an amazing result with an unusual solvent.

My mind keeps playing with the idea of an attempt to do the reaction in N.DimethylFormamide (DMF), i don't know why but probably because it is the best solvent i've seen until now for dissolving the bromo ketone. I use it for cleaning everything that has been in contact with the bromoketone and the only thing which really works. However has a high bp (slow evaporation) which might be undesireble
