title: The analytical profile of some 4-methylthioamphetamine (4-MTA) homologues.
abstract: The 4-methylthioamphetamine (4-MTA) is a sulphur-containing amphetamine-type stimulant (ATS), which appeared on the illicit market in Europe at the end of 90s. For the purpose of this study, several N-alkyl homologues of 4-MTA, including 4-methylthiomethamphetamine (4-MTMA), 4-methylthioethylamphetamine (4-MTEA), 4-methylthiodimethamphetamine (4-MTDMA), 4-methylthiopropylamphetamine (4-MTPA) and 4-methylthiobutylamphetamine (4-MTBA) were synthesized. The homologues were characterized by means of gas chromatography/mass spectrometry (GC-MS), infrared (IR) spectroscopy and the magnetic resonance spectroscopy ((1)H and (13)C NMR). The gas chromatography and mass spectrometry properties of their acetyl, trifluoroacyl (TFA), pentafluoropropionyl (PFP) and heptafluorobutyryl (HFB) derivatives were also investigated and discussed.
