N-Nitroso desethyl Amiodarone is primarily used as a reference standard in pharmaceutical research and quality control to detect and quantify nitrosamine impurities in amiodarone drug substances and finished products.

Its purpose is to help ensure the safety and regulatory compliance of amiodarone medicines by monitoring the presence of this potentially carcinogenic nitrosamine impurity during manufacturing stability testing and quality assurance.

N-Nitroso desethyl Amiodarone is a nitrosated derivative of desethyl amiodarone the major metabolite of amiodarone and is classified as a nitrosamine impurity that is evaluated because of its potential genotoxic and carcinogenic risk.
