Description
Bromfenac Impurity 35 (CAS CATO-C4X-200235) is a certified pharmaceutical impurity reference standard with the molecular formula C15H9BrNNaO5 and a molecular weight of 386.13 g/mol.
Owing to a salt form, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Bromfenac Impurity 35 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Bromfenac Impurity 35 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.
