Chemical Structure
Description
As a certified reference material (CRM), Empagliflozin impurity 264 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 264 (CAS CATO-C4X-1065264, C14H12ClI) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to chlorine/iodine substitution, a polycyclic aromatic system, Empagliflozin impurity 264 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
