Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 450.91 g/mol gives Empagliflozin impurity 199 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Empagliflozin impurity 199 (CAS CATO-C4X-1065199), a pharmacopoeial impurity reference standard (molecular formula C23H27ClO7, MW 450.91 g/mol) used for the identification and quantification of trace impurities in APIs.
Empagliflozin impurity 199 (C23H27ClO7) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Empagliflozin impurity 199 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.
