Managing the complexities of NDSRI method development: The N-nitroso propranolol case story

In this webinar, Dr Marian Twohig, Principal Scientist at Waters Corporation, will provide an overview of the more recent progress around N-nitrosamine regulations.

With the latest regulatory updates encompassing a pragmatic and structural related approach to determining the risk of N-nitrosamine impurities in pharmaceuticals, there remains the ongoing need for pharmaceutical manufacturers to consistently mitigate and control levels of these impurities in new and existing products. When required, analytical testing plays an important role in ensuring levels remain below regulatory acceptance thresholds.

Driven by the latest regulatory guidelines, Dr Twohig will share a comprehensive overview of the development of an analytical methodology for the quantification of N-nitroso propranolol in propranolol, citing unexpected challenges and the resolutions that lead to robust method optimisation beyond regulatory required thresholds.

Key learning objectives:

  • Align analytical method optimisation to current regulatory guidance
  • The importance of high-quality chromatographic methods to facilitate ease of API and isomeric impurity resolution
  • Accessible approaches in tandem quadrupole mass spectrometry solutions supporting the investigation and tentative identification of unexpected peaks and other method optimisation challenges.
