Chemical Structure
Description
The occurrence of Cholecalciferol Impurity 15 is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
As a process- or degradation-related impurity, Cholecalciferol Impurity 15 (CAS 42607-12-5, C27H44O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Cholecalciferol Impurity 15 (C27H44O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Cholecalciferol Impurity 15 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.
