Chemical Structure

Eldecalcitol Impurity 70 CAS CATO-C4X-214070 chemical structure

Description

The occurrence of Eldecalcitol Impurity 70 is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Eldecalcitol Impurity 70 (CAS CATO-C4X-214070) is a certified pharmaceutical impurity reference standard with the molecular formula C41H69O5PSi3 and a molecular weight of 757.23 g/mol.

The molecular framework of Eldecalcitol Impurity 70 (C41H69O5PSi3) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Eldecalcitol Impurity 70 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.
