Chemical Structure

Roxadustat Impurity 102 CAS CATO-C4X-2213102 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 409.44 g/mol gives Roxadustat Impurity 102 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Roxadustat Impurity 102 (CAS CATO-C4X-2213102), a pharmacopoeial impurity reference standard (molecular formula C22H23N3O5, MW 409.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C22H23N3O5, Roxadustat Impurity 102 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 409.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Roxadustat Impurity 102 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.
