A new pyrazole-carboxamide type synthetic cannabinoid, AB-CHFUPYCA (1), was detected in illegal herbal products by our ongoing survey in Japan. The structure of 1 was identified by gas chromatography–mass spectrometry (GC–MS), liquid chromatography–mass spectrometry (LC–MS), liquid chromatography–high-resolution-mass spectrometry (LC–HR-MS) and nuclear magnetic resonance (NMR) analyses. Compound 1 showed a molecular weight of 400, and accurate mass measurement using LC–HR-MS revealed its…

Identification and analytical characterization of six synthetic cannabinoids NNL-3, 5F-NPB-22-7N, 5F-AKB-48-7N, 5F-EDMB-PINACA, EMB-FUBINACA, and EG-018.

The analytical characterization of these six synthetic cannabinoids was described, so as to assist forensic laboratories in identifying these compounds or other substances with similar structure in their case work.

Analytical differentiation of quinolinyl- and isoquinolinyl-substituted 1-(5-fluoropentyl)-1H-indole-3-carboxylates: 5F-PB-22 and its ten isomers

This is the first report on mass spectrometric differentiation of 5F-PB-22 and its ten isomers and the analytical properties of these molecules and methods of differentiation are reported.

The synthesis and characterization of the 'research chemical' N-(1-amino-3-methyl-1-oxobutan-2-yl)-1-(cyclohexylmethyl)-3-(4-fluorophenyl)-1H-pyrazole-5-carboxamide (3,5-AB-CHMFUPPYCA) and differentiation from its 5,3-regioisomer.

The pyrazole core indicates a bioisosteric replacement of an indazole ring that is frequently associated with synthetic cannabinoids of the PINACA, FUBINACA, and CHMINACA series and both isomers were synthesized using two specific routes which supported the correct identification of the 'research chemical' as 3,5-AB-CHMFUPPYCA.
