Eldecalcitol Impurity 52 CAS CATO-C4X-214052

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 52 (CAS CATO-C4X-214052) is a certified pharmaceutical impurity reference standard with the molecular formula C19H36O2 and a molecular weight of 296.49 g/mol.

Based on its molecular formula C19H36O2, Eldecalcitol Impurity 52 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 296.49 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.

As a certified reference material (CRM), Eldecalcitol Impurity 52 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.
