Abstract

Physical constants and instrumental data (melting point [mp], thin-layer chromatography [TLC] [R^f], gas chromatography [GC] [R^t], [α]D25, ¹H- and ¹³C-nuclear magnetic resonance [NMR], infrared (IR), 70-eV, electron impact-mass spectroscopy [EI-MS], color, and microcrystalline tests) are reported for the individual stereoisomers, racemates, and corresponding hydrochloride salts of 4-methylaminorex (2-amino-4-methyl-5-phenyl-Δ²-oxazoline, 4,5-dihydro-4-methyl-5-phenyl-2-oxazolamine, McN-822, “U4Euh,” “ICE”). The data allow identification and differentiation of illicit samples of 4-methylaminorex.

Keywords:
forensic science, 4-methylaminorex (U4Euh), 2-amino-4-methyl-5-phenyl-Δ2-oxazoline, stereoisomers, anorectic agent, CNS stimulant, Controlled Substances Act
