Abstract:
In the last 10 years, the abuse of designer drugs has proliferated due to the ease of purchase on the Internet. Our research laboratory collaborates with the Financial Police (GdF) analyzing drugs of abuse on behalf of the Court (Procura della Repubblica––Tribunale di Busto Arsizio). Nine products sold on the Internet and suspected to contain illegal substances were brought to our laboratory after a seizure at the Malpensa Airport in Northern Italy. After first routine analyses carried out by thin-layer chromatography (TLC) and gas chromatography/flame ionization detection (GC/FID), we were able to exclude all “classical” drugs and common new psychoactive substances (NPSs). This prompted us to deeply analyze the unknown product to identify it by different analytical techniques. The structure of the unknown compound was elucidated by gas chromatography/mass spectrometry (GC/MS), liquid chromatography/mass spectrometry (LC/MS), accurate mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. This characterization allowed us to identify the unknown substance as a new designer drug thiothinone, [2-(methylamino)-1-(2-thienyl)-1-propanone]. The X-ray powder diffraction (XRPD) pattern and the analytical data presented herein can provide valid support to forensic chemists who may encounter this “legal high” in caseworks. To our knowledge, this is the first scientific disclosure of thiothinone from dubious products.
