Chemical Structure
Description
As a certified reference material (CRM), Eldecalcitol Impurity 62 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 Eldecalcitol Impurity 62 (CAS CATO-C4X-214062), a pharmacopoeial impurity reference standard (molecular formula C22H27O4P, MW 386.42 g/mol) used for the identification and quantification of trace impurities in APIs.
Eldecalcitol Impurity 62 (C22H27O4P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
