D-tartaric acid, and importantly Cas (147-71-7), will preferentially precipitate D-Meth crystals. 13 g of D-tartaric acid was dissolved in 52 ml of methanol, then poured into 20 g of DL-methanol oil and stirred for 6 hours to generate diastereomers (D acid-D base salt)Crystals, (D acid-L base...

Introduction In this article, a detailed description of d-methamphetamine hydrochloride synthesis via tartaric acid was represented. This isomer separation approach is the easiest and most popular among clandestine chemists. It's reasoned by cheap and affordable d,l-Tartaric acid (CAS 133-37-9)...

Looking for D-tartaric acid cas 147-71-7 in relatively small amount (just for tests, 500 gr enough) in the EU with price little less than 200 EUR per 100 gr))))) Is it possible to get?
