Eldecalcitol Impurity 36 CAS 1101133-55-4

Description

Compared with other compounds in its class, the molecular weight of 394.71 g/mol gives Eldecalcitol Impurity 36 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Eldecalcitol Impurity 36 (CAS 1101133-55-4, C24H46O2Si) 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 36 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 36 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.
