1 3 * * * * * Analytical data of designer drugs of synthetic phenethylamines Ryosuke SASAKI*, Miho KAT*, Tsuyoshi MATSUMT*, Akira UDAGAWA* and Ryuichi MATSUZAKI* *Tokyo Customs Laboratory , Aomi, Koto-ku, Tokyo Japan In recent years, so-called designer drugs, which are chemicals whose structures are similar to illicit drugs, have been widely distributed and abused in Japan. Synthetic phenethylamines, one group of designer drugs, have similar structures to stimulants, and also stimulate the central nervous system like stimulants. In this study, we classified synthetically produced phenethylamine samples according to their chemical structures, and analyzed them using an infrared spectrometer (IR), gas chromatograph mass spectrometer (GC-MS), liquid chromatograph mass spectrometer coupled with photodiode array detector (LC-PDA-MS) and nuclear magnetic resonance (NMR) spectrometer IR GC-MS LC-PDA-MS NMR Table 1 Fig TFA TFAA *
