Impurity Profiling Strategy

Impurity profiling strategy systematically identifies, quantifies, and characterises manufacturing-related and degradation impurities. Forced degradation studies generate representative impurity profiles. Chromatographic separation isolates pure impurity standards. Structure elucidation via mass spectrometry and NMR identifies molecules. Risk assessment prioritises high-concern impurities.

Regulatory submissions include comprehensive impurity profiles. Specification limits establish acceptable impurity levels. Stability monitoring detects emerging impurities requiring investigation. Manufacturing improvements reduce impurity formation. Post-approval monitoring ensures continued compliance.
