Chemical Structure

Empagliflozin Impurity 105 CAS 915095-90-8 chemical structure

Description

As a certified reference material (CRM), Empagliflozin Impurity 105 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Empagliflozin Impurity 105 (CAS 915095-90-8), a pharmacopoeial impurity reference standard (molecular formula C17H16BrClO2, MW 367.66 g/mol) used for the identification and quantification of trace impurities in APIs.

Empagliflozin Impurity 105 (C17H16BrClO2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
