PMK Glycide powder oil CAS 28578-16-7

PMK Glycide powder oil is an analytical reference standard categorized as a precursor in the synthesis of methylenedioxy phenethylamines and amphetamines, including 3,4-MDMA.

Is PMK ethyl glycinate the same as PMK methyl glycinate?

PMK ethyl glycinate (Cas 28578-16-7) is an analytical reference standard categorized as a precursor in the synthesis of methylenedioxy phenethylamines and amphetamines, including 3,4-MDMA. This product is intended for research and forensic applications.

There are two specifications: PMK methyl Glycidate powder Cas 13605-48-6, PMK ethyl Glycidate oil Cas 28578-16-7.

Most routers for the synthesis of 3,4-methylenedioxymethamphetamine (MDMA) start from compounds containing 3,4-methylenedioxyphenyl rings, such as safrole, isosafrole, piperonal, Bromo safrole, and piperonal methyl ketone (piperonal methyl ketone, PMK), etc.PMK is currently the most important precursor compound for the synthesis of MDMA in underground processing plants, and MDMA can be prepared by the simple Lukat method or reductive amination method.

Since 2010, some underground processing plants of MDMA have gradually discovered that a PMK derivative, PMK methyl glycidate, is used to produce PMK  , and then MDMA is produced

The structural formula of PMK methyl glycate

H-NMR and 13 C-NMR spectra (Figures 3~4) of the samples were assigned, and each signal was consistent with the structure of PMK methyl glycinate . The group peaks are the signal after the benzene ring is substituted by the 1, 3, and 4 positions; δ 6.04 is a single, which is the methylene signal directly connected to two oxygen atoms; two singlets of δ 4.28 and δ 3.73 are the connection, respectively The methine and methyl signals of the oxygen atom;

the single peak of δ 1.24 is the methyl signal connected to the tertiary carbon; the four signals in the high-field region of the carbon spectrum are the primary carbon, the primary carbon connected to an oxygen atom, and the tertiary carbon. and quaternary carbon signals; δ 101.67 is the secondary carbon signal connecting two oxygen atoms; the six signals of δ 107.44~147.77 are the signals of six carbon atoms on the benzene ring; δ 170.96 is the carbonyl carbon signal of methyl ester.
