Chemical Structure
Description
CATO supplies Empagliflozin Impurity 149 (CAS CATO-C4X-1065149), a pharmacopoeial impurity reference standard (molecular formula C23H28O7, MW 416.46 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Empagliflozin Impurity 149 (C23H28O7) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
