Chemical Structure

Bromfenac Impurity 78 CAS CATO-C4X-200278 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 302.17 g/mol gives Bromfenac Impurity 78 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Bromfenac Impurity 78 (CAS CATO-C4X-200278, C15H12BrNO) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Bromfenac Impurity 78 (C15H12BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
