Chemical Structure

Empagliflozin Impurity 99 CAS 5469-16-9 chemical structure

Description

As a certified reference material (CRM), Empagliflozin Impurity 99 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 99 (CAS 5469-16-9, C4H6O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Empagliflozin Impurity 99 (C4H6O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
