Screening and Quantification of the Synthetic Cannabinoid Receptor Agonist 5F‐MDMB‐PINACA From Seized Prison Paper Using Ultraperformance Liquid Chromatography–Mass Spectrometry Approaches

open access: yesDrug Testing and Analysis, EarlyView.
Synthetic cannabinoid receptor agonists are being infused on paper and illicitly introduced into prisons through mail correspondence. An approach to quantify and map the synthetic cannabinoid 5F‐ADB on a seized paper sample from a UK prison was determined using ultraperformance liquid chromatography–quadrupole Dalton–mass spectrometry.

Identification of Three Novel Tetrahydrocannabinol Analogs in the European Market

open access: yesDrug Testing and Analysis, EarlyView.
The major isolated ingredient of “CB9” was identified as [2‐(E)‐propen‐1‐yl]‐Δ8‐tetrahydrocannabinol‐acetate of “tresconol” as [2‐propen‐2‐yl]‐Δ9‐tetrahydrocannabinol and of “CBx” as [2‐propen‐2‐yl]‐Δ8‐tetrahydrocannabinol. These compounds have no available spectroscopic or chromatographic data and have never been identified in Cannabis plants, and ...

Quantitative Investigation of Nitrosamine Drug Substance‐Related Impurities (NDSRIs) Under Artificial Gastric Conditions by Liquid Chromatography–Tandem Mass Spectrometry and Structure–Activity Relationship Analysis

open access: yesDrug Testing and Analysis, EarlyView.
The study provides information about the impact of physiological gastric conditions on the unbeneficial occurrence of nitrosamine drug substance–related impurities (NDSRIs). Both main factors for nitrosation in the form of acidic conditions and the presence of nitrite were adequately chosen for triggering the conversion of drug compounds into NDSRIs ...
