Chemical Structure

Eldecalcitol Impurity 31 CAS CATO-C4X-214031 chemical structure

Description

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.

Eldecalcitol Impurity 31 (CAS CATO-C4X-214031) is a certified pharmaceutical impurity reference standard with the molecular formula C25H50O2Si and a molecular weight of 410.75 g/mol.

Structurally, Eldecalcitol Impurity 31 (C25H50O2Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 410.75 g/mol, it falls into the moderately-high-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.

CATO manufactures Eldecalcitol Impurity 31 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
