Chemical Structure

Calcitriol Impuirty 57 CAS CATO-C4X-151057 chemical structure

Description

As a certified reference material (CRM), Calcitriol Impuirty 57 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.

CATO supplies Calcitriol Impuirty 57 (CAS CATO-C4X-151057), a pharmacopoeial impurity reference standard (molecular formula C25H48OSi, MW 392.74 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Calcitriol Impuirty 57 (C25H48OSi) is characterized by 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.

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.
