Chemical Structure
Description
The occurrence of Bromfenac Impurity 2 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
As a process- or degradation-related impurity, Bromfenac Impurity 2 (CAS CATO-C4X-20022, C30H18Br2N2O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Based on its molecular formula C30H18Br2N2O3, Bromfenac Impurity 2 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.
CATO manufactures Bromfenac Impurity 2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
