Abstract

2-Chloroacetophenone (CN) and o-chlorobenzylidene malononitrile (CS) are the most common chemical agents used as lacrimators in the United States. There is a lack of complete spectral data on these compounds in the literature. Spectral data (ultraviolet, fluorescence, proton nuclear magnetic resonance, and infrared) and a gas-liquid chromatographic/mass spectrometric method are presented that differentiate and identify CN and CS. These methods and data were used to identify a forensic science specimen from an accidental intoxication.
