  • Synthetic Cannabinoid structure classification using the bridge carbonyl frequency in vapor phase
    Patent number: 10782271
    Abstract: Synthetic Cannabinoids are the most complex branch of designer drugs encountered in forensic chemistry. A screening method has been developed that can accurately identify the correct structural category of an unknown Synthetic Cannabinoid. Knowledge of this information is very important when no reference data or standards are available since certain sub-categories contain Schedule I Controlled Dangerous Substances. The Bridge portion of these molecules present a unique carbonyl band cluster within a small 200 wavenumber interval of the mid-infrared region that can only exist in vapor phase through GC/FTIR light-pipe technology or heated static vapor cell FTIR. This special relationship is not applicable to any other forms of solid phase vibrational spectroscopy (FTIR, RAMAN) including GC/FTIR solid-deposit techniques.
