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 ...
