Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 396.65 g/mol gives (R)-Vitamin D2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (R)-Vitamin D2 (CAS 116559-84-3), a certified reference material (molecular formula C28H44O, MW 396.65 g/mol) for analytical method development and quality control.
(R)-Vitamin D2 (C28H44O) 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
