N-nitrosamines are potential carcinogenic impurities that can pose a risk to human health when exposed over an extended period. Whilst global regulations are evolving, where there is risk of N-nitrosamine formation in drug products, analytical testing is still necessary. With this continues a requirement for customized and optimized sample extraction, chromatographic separation, and often flexible mass spectrometry acquisition, supporting a range of regulatory set threshold limits, for both small and complex N-nitrosamines. Small and complex N-nitrosamines (NDSRI) present common challenges, such as extraction efficiency and robust detection, whether quantification is to the trace level or to higher limits of sensitivity. Specific challenges also arise, such as minimizing low mass interference for small N-nitrosamines or managing structural similarities to the API and isomeric separation for NDSRIs. Minimizing contamination and N-nitrosamine formation during sample preparation is always critical. In this webinar, Dr. Padmakar Wagh, Associate Director: Applications at Waters Corporation and Hugo Cortés, a senior specialist in mass spectrometry at Waters Corporation, will demonstrate strategies for developing robust quantification assays for both small N-nitrosamines and NDSRI in drug products. They will address the typical challenges encountered for both types of N-nitrosamines, and will include practical examples of quality method development and take-away method development strategies from Waters laboratories.
