Eldecalcitol Impurity 53 CAS 1308304-91-7 chemical structure

Description

CATO manufactures Eldecalcitol Impurity 53 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.

CATO supplies Eldecalcitol Impurity 53 (CAS 1308304-91-7), a pharmacopoeial impurity reference standard (molecular formula C23H44O2Si, MW 380.68 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Eldecalcitol Impurity 53 (C23H44O2Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
