Chemical Structure

Ergocalciferol Impurity 01 CAS 55812-80-1 chemical structure

Description

As a process- or degradation-related impurity, Ergocalciferol Impurity 01 (CAS 55812-80-1, C19H32O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Ergocalciferol Impurity 01 (C19H32O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Ergocalciferol Impurity 01 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.
