Description
As a certified reference material (CRM), Brivaracetam Impurity 212 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 212 (CAS CATO-C4X-2007212) is a certified pharmaceutical impurity reference standard with the molecular formula C30H47Br2NO5 and a molecular weight of 661.51 g/mol.
The molecular framework of Brivaracetam Impurity 212 (C30H47Br2NO5) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
