Text Abstract (this page) Full Text - English (private) Show Articles by Borth S Hansel W Rosner P Junge T Article IDs Erowid RefID: 467 PubMedID: unknown Collections Hofmann Collection MDMA Collection All References	Abstract Numerous abused drugs of the 3,4-methylenedioxymetamphetamine (MDMA; Ecstasy; N-methyl-1-(3,4-methylenedioxyphenyl)-2-propaneamine) type and various alkyl chain- and aromatic ring-substituted isomers give very similar electron ionization (EI) mass spectra. This seriously affects the analysis of especially ring regioisomeric drug variants. Using collision-induced dissociation (CID) (argon) under EI and chemical ionization, the mass spectra of 18 2,3- and 3, 4-methylenedioxy ring-substituted phenylethylamines were recorded. These techniques permitted an unequivocal differentiation of all studied ring regioisomeric methylenedioxyphenylethylamines. CID mass spectrometry therefore appear to be a reliable tool to establish the kind of ring substitution pattern in regioisomeric methylenedioxyphenalkylamines. Copyright 2000 John Wiley & Sons, Ltd.
