Differentiation of 2-and 6-isomers of (2-dimethylaminopropyl)benzofuran by tandem mass spectrometryReliable identification of new psychoactive substances of 2-(2-methylaminopropyl) benzofuran and 6-(2-methylaminopropyl)benzofuran is problematic when analyzing by gas chromatography-mass spectrometry method. It found that these two isomers can be reliably differentiated by MS/MS spectra obtained by collision-induced dissociation of their protonated molecules.Key words: new psychoactive substances; amphetamine derivatives; chromatographymass spectrometry method; high-resolution mass spectrometry; EI spectra; CID spectra. В. А. Шевырин 1,2 Дифференциация 2-и 6-изомеров (2-метиламинопропил)бензофурана методом тандемной масс-спектрометрииДостоверная идентификация новых психоактивных соединений 2-(2-метиламинопропил) бензофурана и 6-(2-метиламинопропил)бензофурана проблематична при проведении ана-лиза методом хроматомасс-спектрометрии. Установлено, что эти два изомера могут быть надежно дифференцированы по МС/МС спектрам, полученным в результате диссоциации, индуцируемой соударением, их протонированных молекул.Ключевые слова: психоактивные соединения; производные амфетамина; хроматомасс-спектрометрия; масс-спектрометрия высокого разрешения, масс-спектры электронной иони-зации, МС/МС спектры.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
