Chemical Structure
Description
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 supplies Flurbiprofen Impurity 161 (CAS CATO-C4X-1444161), a pharmacopoeial impurity reference standard (molecular formula C15H13FO2, MW 244.26 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, Flurbiprofen Impurity 161 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Flurbiprofen Impurity 161 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.
