Eldecalcitol Impurity 2 CAS 201854-22-0 chemical structure

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 2 (CAS 201854-22-0) is a certified pharmaceutical impurity reference standard with the molecular formula C30H50O5 and a molecular weight of 490.72 g/mol.

Based on its molecular formula C30H50O5, Eldecalcitol Impurity 2 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 490.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Eldecalcitol Impurity 2 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.
