Calcipotriol Impurity 25 CAS CATO-C4X-122225

Description

Compared with other compounds in its class, the molecular weight of 412.60 g/mol gives Calcipotriol Impurity 25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Calcipotriol Impurity 25 (CAS CATO-C4X-122225), a pharmacopoeial impurity reference standard (molecular formula C27H40O3, MW 412.60 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C27H40O3, Calcipotriol Impurity 25 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 412.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Calcipotriol Impurity 25 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.
