Description
As a certified reference material (CRM), Brivaracetam Impurity 59 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Brivaracetam Impurity 59 (CAS CATO-C4X-200759) is a certified pharmaceutical impurity reference standard with the molecular formula C17H20N2O3 and a molecular weight of 300.35 g/mol.
Based on its molecular formula C17H20N2O3, Brivaracetam Impurity 59 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
