Brivaracetam Impurity 129 CAS CATO-C4X-2007129 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Brivaracetam Impurity 129.

Brivaracetam Impurity 129 (CAS CATO-C4X-2007129) is a certified pharmaceutical impurity reference standard with the molecular formula C9H16O2 and a molecular weight of 156.22 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Brivaracetam Impurity 129 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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 129 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.
