Description

Compared with other compounds in its class, the molecular weight of 428.65 g/mol gives 24(R,S),25-Dihydroxy vitamin D2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

24(R,S),25-Dihydroxy vitamin D2 (CAS 71183-99-8), molecular formula C28H44O3 and molecular weight 428.65 g/mol, is a CATO reference standard with documented purity and traceability.

24(R,S),25-Dihydroxy vitamin D2 (C28H44O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 24(R,S),25-Dihydroxy vitamin D2 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.
