Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 319.98 g/mol gives Ozagrel Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ozagrel Impurity 31 (CAS CATO-C4X-197131) is a certified pharmaceutical impurity reference standard with the molecular formula C10H8Br2O2 and a molecular weight of 319.98 g/mol.
Based on its molecular formula C10H8Br2O2, Ozagrel Impurity 31 contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 319.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Ozagrel Impurity 31 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.
