Empagliflozin Impurity 28 CAS 19094-56-5

Description

The occurrence of Empagliflozin Impurity 28 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Empagliflozin Impurity 28 (CAS 19094-56-5), a pharmacopoeial impurity reference standard (molecular formula C7H4ClIO2, MW 282.46 g/mol) used for the identification and quantification of trace impurities in APIs.

Empagliflozin Impurity 28 (C7H4ClIO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. 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.

CATO manufactures Empagliflozin Impurity 28 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.
