Description
As a certified reference material (CRM), Bromfenac Impurity 32 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.
Bromfenac Impurity 32 (CAS CATO-C4X-200232) is a certified pharmaceutical impurity reference standard with the molecular formula C30H18Br2N2O3 and a molecular weight of 614.28 g/mol.
Based on its molecular formula C30H18Br2N2O3, Bromfenac Impurity 32 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 614.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
