Dapagliflozin Impurity 133 CAS CATO-C4X-1138133

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 Dapagliflozin Impurity 133 (CAS CATO-C4X-1138133), a pharmacopoeial impurity reference standard (molecular formula C5H5NO2, MW 111.10 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Dapagliflozin Impurity 133 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 111.10 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).

As a certified reference material (CRM), Dapagliflozin Impurity 133 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.
