Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 403.66 g/mol gives Calcifediol D3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Calcifediol D3 (CAS 1262843-45-7) is a high-purity analytical reference standard with the molecular formula C27H41D3O2 and a molecular weight of 403.66 g/mol.
Calcifediol D3 (C27H41D3O2) contains deuterium isotope labeling, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
