Empagliflozin Impurity 121 CAS CATO-C4X-1065121

Description

Compared with other compounds in its class, the molecular weight of 915.80 g/mol gives Empagliflozin Impurity 121 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Empagliflozin Impurity 121 (CAS CATO-C4X-1065121), a pharmacopoeial impurity reference standard (molecular formula C46H52Cl2O15, MW 915.80 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, chlorine substitution, a polycyclic aromatic system, Empagliflozin Impurity 121 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 915.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Empagliflozin Impurity 121 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.
