Different runs of what I would asume is the "commercial" synthesis of both ketamine and MXE do not generate different "ratios" of enatiomers. They produce racemic product 100% of the time unless you use chiral starting materials. You have to start doing wacky chiral synthesis or do crystallization with L-tartaric acid or something to generate enantiomerically pure MXE/Ketamine. This is how Ketaset-S is produced, I think. To the best of my knowledge, unless the guys who make esketamine are blending the R-ketamine into other batches of "normal" ketamine, all commericial and street ketamine that isn't specifically S or R should be racemic.
Perhaps you could build/buy a polarimeter and figure out the specific rotation? My money's on it being 0. I think it's set and setting, or tolerance.
It could also be your supposedly "reliable" vendors are shipping fine white sand as MXE. You never know without some lab skills.
I mean I have very limited chemistry knowledge I was just wondering why there would be differences between batches of MXE. I mean really I could be getting a totally different product and be completely oblivious as is the danger of buying miscellaneous white powders off the internet. Thank you for your reply though.
