Chemical Structure
Description
The occurrence of Empagliflozin Impurity 25 is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
As a process- or degradation-related impurity, Empagliflozin Impurity 25 (CAS 915095-89-5, C17H16BrClO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Empagliflozin Impurity 25 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 367.66 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).
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 25 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.
