Analytical quality by design aided stability indicating a robust ultra‐performance liquid chromatographic technique for the quantification of sonidegib and its organic impurities in bulk drug substance

Abstract

AbstractA simple quality by design aided stability indicating method was developed for quantification of sonidegib (SONI) and its process related impurities using on ultra‐performance liquid chromatography in bulk drug substance. AutoChrom and Design‐Expert software were used to predict physicochemical properties, draw Ionization graphs, and generate analytical target profile. SONI was subjected to forced degradation conditions, such as oxidative, acid hydrolysis, base hydrolysis, hydrolytic, thermal, and photolytic hydrolysis. All degradation products and process contaminants were separated using an Acquity Ethylene Bridged Hybrid C18 column in gradient elution mode with a mobile phase containing 0.02 M ammonium acetate buffer and acetonitrile: methanol (80:20 v/v). The predicted physicochemical properties are accurate and they facilitated for selection of robust conditions in development of chromatographic method with minimal trials. The developed method can be used for quantification of drug and its process related impurities in bulk drugs.
