Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 773.26 g/mol gives Eldecalcitol Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Eldecalcitol Impurity 15 (CAS CATO-C4X-214015, C42H73O5PSi3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Eldecalcitol Impurity 15 (C42H73O5PSi3) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
As a certified reference material (CRM), Eldecalcitol Impurity 15 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.
