Chemical Structure
Description
As a certified reference material (CRM), Brivaracetam impurity 106 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 106 (CAS CATO-C4X-2007106) is a certified pharmaceutical impurity reference standard with the molecular formula C9H17BrO2 and a molecular weight of 237.13 g/mol.
Brivaracetam impurity 106 (C9H17BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
