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 (H-1 and C-13 NMR). The gas chromatography and mass spectrometry properties of their acetyl, trifluoroacyl (TFA), pentafluoropropionyl (PFP) and heptafluorobutyryl (HFB) derivatives were also investigated and discussed.
