Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Empagliflozin impurity 232.
Empagliflozin impurity 232 (CAS CATO-C4X-1065232) is a certified pharmaceutical impurity reference standard with the molecular formula C17H15ClI2O2 and a molecular weight of 540.56 g/mol.
Empagliflozin impurity 232 (C17H15ClI2O2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 232 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.
