Title
(EN) Nuclear magnetic resonance implemented synthetic indole and indazole cannabinoid detection, identification, and quantification
Abstract
(EN)

The present invention provides a method for detecting synthetic indole and indazole cannabinoids in a sample known or suspected to contain a synthetic indole or indazole cannabinoid in the absence of chromatography. A deuterated solvent is added to the solid sample, creating a suspension. The synthetic cannabinoid is detected in the suspension by analysis of the sample NMR spectrum. When one-dimensional proton NMR is used, detection of a first peak between 8.00 and 8.50 ppm and a second peak between 4.00 and 4.40 ppm, indicates the presence of a synthetic indole or indazole cannabinoid. When two-dimensional Correlation Spectroscopy (COSY) NMR is used, detection of a first spot between 6.50 and 9.00 ppm and a second spot between 1.50 and 4.50 ppm indicates the presence of a synthetic indole or indazole cannabinoid.
