Brivaracetam Impurity 207 CAS CATO-C4X-2007207

Description

Compared with other compounds in its class, the molecular weight of 249.73 g/mol gives Brivaracetam Impurity 207 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Brivaracetam Impurity 207 (CAS CATO-C4X-2007207), a pharmacopoeial impurity reference standard (molecular formula C11H20ClNO3, MW 249.73 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Brivaracetam Impurity 207 (C11H20ClNO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 207 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.
