Chemical Structure
Description
As a process- or degradation-related impurity, Flurbiprofen Impurity 113 (CAS CATO-C4X-1444113, C33H30F2O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Flurbiprofen Impurity 113 (C33H30F2O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Flurbiprofen Impurity 113 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.
