Description
Empagliflozin Impurity 151 (CAS CATO-C4X-1065151) is a certified pharmaceutical impurity reference standard with the molecular formula C21H21IO5 and a molecular weight of 480.29 g/mol.
The molecular framework of Empagliflozin Impurity 151 (C21H21IO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. 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. 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 151 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.
