Chemical Structure

Eldecalcitol Impurity 48 CAS 197647-61-3 chemical structure

Description

Structurally, Eldecalcitol Impurity 48 (C13H24O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 196.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Eldecalcitol Impurity 48 (CAS 197647-61-3) is a certified pharmaceutical impurity reference standard with the molecular formula C13H24O and a molecular weight of 196.33 g/mol.

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 48 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.
