Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Eldecalcitol Impurity 26.
As a process- or degradation-related impurity, Eldecalcitol Impurity 26 (CAS CATO-C4X-214026, C54H106O5Si4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Eldecalcitol Impurity 26 is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 947.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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 26 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.
