Chemical Structure

Flomoxef Impurity 52 CAS CATO-C4X-138252 chemical structure

Description

As a certified reference material (CRM), Flomoxef Impurity 52 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.

CATO supplies Flomoxef Impurity 52 (CAS CATO-C4X-138252), a pharmacopoeial impurity reference standard (molecular formula C15H18F2N6O8S2, MW 512.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Flomoxef Impurity 52 (C15H18F2N6O8S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 512.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.
