Description
CATO supplies Brivaracetam Impurity 163 (CAS CATO-C4X-2007163), a pharmacopoeial impurity reference standard (molecular formula C9H16O4, MW 188.22 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Brivaracetam Impurity 163 (C9H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
As a certified reference material (CRM), Brivaracetam Impurity 163 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.
