Description
Summary:The results of chromatographic study of psychoactive drugs emerged in recent years on the illicit market are rendered in the article. 18 phenethylamine derivatives were identified by means of gas-liquid chromatography with mass selective detection and their chromatographic retention indexes were defined. The known regularities of fragmentation of molecules of saturated aliphatic amines in electron impact ionization were confirmed during the study of the mass spectra of the known phenethylamine derivatives and used to decrypt the mass spectra of 3,4-methylenedioxy-N-methcathinone, 4-methylmethcathinones and 4-methylethcathinones. The indicators of chromatographic retention in the solvent system of chloroform-acetone-ethanol-25% ammonia solution (20:20:3:1) were identified by thin layer chromatography on silica gel for these compounds.Key words: psychoactive substance, phenethylamine derivatives, identification, chromatography, mass spectrometry, fragmentation.(Russian)DOI: http://dx.doi.org/10.15826/analitika.2014.18.2.007 S.V.

Методом газо-жидкостной хроматографии с масс-селективным детектированием идентифицировано 18 производных фенилэтиламина и определены их хроматографические индексы удерживания. Известные закономерности фрагментации молекул насыщенных алифатических аминов при ионизации электронным ударом подтверждены в ходе изучения масс-спектров известных производных фенилэтиламина и использованы при расшифровке масс-спектров 3,4-метилендиокси-N-меткатинона, 4-метилметкатинона и 4-метилэткатинона. Методом тонкослойной хроматографии на силикагеле для этих соединений определены ...
