摘要
Recently, novel psychoactive drugs for human abuse such as amphetamines, phenethylamines, benzofuries, and tryptamines, cathinones have gained high popularity. These designer drugs are mainly sold via online stores as "bath salts" and are labeled "not for human consumption." Due to the novelty of the compounds, only a little information about pharmacology, toxicology, and the long-term damage they may cause is available. Moreover, there are only few analytical methods for their identification and analysis. Among new cathinone derivatives, 1-(3,4-dimethoxyphenyl)-2-(ethylamino)pentan-1-one (DL-4662), became available via an internet shop. A sample of this compound was purchased and investigated. The first aim of our study was an identity check by NMR spectroscopy and gas chromatography with mass spectrometry. As many of the recreational drugs are chiral and are mainly sold as racemates, a further goal of our research was enantioseparation by gas chromatography with mass spectrometry and high-performance liquid chromatography with UV detection, to prove whether DL-4662 was traded enantiomerically pure or as racemic mixture. Both chiral separation methods showed the presence of a racemate.
