Chemical Structure

Empagliflozin Impurity 311 CAS CATO-C4X-1065311 chemical structure

Description

As a certified reference material (CRM), Empagliflozin Impurity 311 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.

As a process- or degradation-related impurity, Empagliflozin Impurity 311 (CAS CATO-C4X-1065311, C18H18ClIO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Empagliflozin Impurity 311 (C18H18ClIO2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine/iodine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
