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.
本发明提供了一种在不使用色谱法的情况下检测已知或怀疑含有合成吲哚或吲唑大麻素的样品中合成吲哚和吲唑大麻素的方法。向固体样品中加入氚代溶剂,形成悬浮液。通过分析样品的 NMR 光谱来检测悬浮液中的合成大麻素。使用一维质子核磁共振时,如果检测到 8.00 至 8.50 ppm 之间的第一个峰和 4.00 至 4.40 ppm 之间的第二个峰,则表明存在合成吲哚或吲唑大麻素。当使用二维相关光谱(COSY)核磁共振时,检测到 6.50 至 9.00 ppm 之间的第一个光斑和 1.50 至 4.50 ppm 之间的第二个光斑,表明存在合成吲哚或吲唑大麻素。
