Description
Empagliflozin impurity 185 (CAS CATO-C4X-1065185) is a certified pharmaceutical impurity reference standard with the molecular formula C13H7BrFIO and a molecular weight of 405.00 g/mol.
The molecular framework of Empagliflozin impurity 185 (C13H7BrFIO) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Empagliflozin impurity 185 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.
