Description
CATO manufactures Dapagliflozin Impurity 161 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.
CATO supplies Dapagliflozin Impurity 161 (CAS CATO-C4X-1138161), a pharmacopoeial impurity reference standard (molecular formula C58H64Cl2O20, MW 1152.02 g/mol) used for the identification and quantification of trace impurities in APIs.
Dapagliflozin Impurity 161 (C58H64Cl2O20) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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 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.
