Empagliflozin impurity 61 CAS CATO-C4X-1065261

Description

The occurrence of Empagliflozin impurity 61 is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Empagliflozin impurity 61 (CAS CATO-C4X-1065261), a pharmacopoeial impurity reference standard (molecular formula C17H16ClIO2, MW 414.67 g/mol) used for the identification and quantification of trace impurities in APIs.

Empagliflozin impurity 61 (C17H16ClIO2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 61 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.
