Chemical Structure
Description
The molecular framework of Empagliflozin Impurity 151 (C13H7BrClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine/bromine 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.
Empagliflozin Impurity 151 (CAS 915095-85-1) is a certified pharmaceutical impurity reference standard with the molecular formula C13H7BrClFO and a molecular weight of 313.55 g/mol.
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.
