Evocalcet impurity 57 CAS CATO-C4X-248557 chemical structure

Description

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.

CATO supplies Evocalcet impurity 57 (CAS CATO-C4X-248557), a pharmacopoeial impurity reference standard (molecular formula C23H26N2O, MW 346.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Evocalcet impurity 57 (C23H26N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

As a certified reference material (CRM), Evocalcet impurity 57 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.
