[Studies on the identification of psychotropic substances. IX. Preparation and various analytical data of reference standard of new psychotropic substances, N-ethyl methylenedioxyamphetamine, N-hydroxy methylenedioxyamphetamine, mecloqualone, 4-methylaminorex, phendimetrazine and phenmetrazine].

The reference standards of N-Ethyl methylenedioxyamphetamine, N-Hydroxy methylenedioxy-amphetamine, Mecloqualone, 4-Methylaminorex. Phendimetrazine and Phenmetrazine were chemically prepared from commercial chemicals. Their purities determined by HPLC were more than 99.8%. The standard spectra and chromatograms of the standards such as TLC, UV, IR, HPLC, GC/MS and NMR were measured. For the identification of these six drugs in forensic laboratory, their mass fragmentation and NMR spectra were discussed.
