Chemical Structure

Brivaracetam Impurity 191 CAS CATO-C4X-2007191 chemical structure

Description

As a certified reference material (CRM), Brivaracetam Impurity 191 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.

As a process- or degradation-related impurity, Brivaracetam Impurity 191 (CAS CATO-C4X-2007191, C10H19BrO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Brivaracetam Impurity 191 (C10H19BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
