Reliable HPLC/UV Quantification of Nitrosamine Impurities in Valsartan and Ranitidine Drug Substances
This study demonstrates the reliable quantification of six nitrosamine impurities (NDMA, NDEA, NEIPA, NDIPA, NDBA, and NMBA) in valsartan and NDMA in ranitidine by UV detection, with the added benefit of mass confirmation by mass spectral data using an ACQUITY QDa Mass Detector.
