Description
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.
Empagliflozin Impurity 134 (CAS CATO-C4X-1065134) is a certified pharmaceutical impurity reference standard with the molecular formula C17H14Br2O3 and a molecular weight of 426.10 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, Empagliflozin Impurity 134 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Empagliflozin Impurity 134 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.
