Description
CATO supplies Bifendate impurity 10 (CAS CATO-C4X-255510), a pharmacopoeial impurity reference standard (molecular formula C19H16O9, MW 388.32 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, Bifendate impurity 10 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Bifendate impurity 10 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.
