Chemical Structure

Eldecalcitol Impurity 25 CAS CATO-C4X-214025 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 25 (CAS CATO-C4X-214025) is a certified pharmaceutical impurity reference standard with the molecular formula C36H64O5Si and a molecular weight of 604.99 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Eldecalcitol Impurity 25 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 604.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures Eldecalcitol Impurity 25 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.
