Description
As a certified reference material (CRM), Bromfenac Impurity 17 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.
CATO supplies Bromfenac Impurity 17 (CAS CATO-C4X-200217), a pharmacopoeial impurity reference standard (molecular formula C15H9BrClNO2, MW 350.59 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Bromfenac Impurity 17 (C15H9BrClNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
