Abstract:Background and Aim: Process impurities may adversely affect the efficacy, excellent quality, and safety of pharmaceutical drugs. Ultimately, the purpose of this research work was to develop and validate a LC-MS/MS-based method for determining the Vinamidinium hexafluorophosphate impurity (VHP) in Etoricoxib in a simple, specific, accurate, and precise manner. Materials and Methods: To elute the Vinamidinium hexafluorophosphate impurity in Etoricoxib at a flow rate of 0.5mL/min within 20.0 min of runtime, a Sym… Show more
