Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution, Empagliflozin Impurity 57 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 480.94 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).
CATO supplies Empagliflozin Impurity 57 (CAS CATO-C4X-106557), a pharmacopoeial impurity reference standard (molecular formula C24H29ClO8, MW 480.94 g/mol) used for the identification and quantification of trace impurities in APIs.
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 manufactures Empagliflozin Impurity 57 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
