Compared with other compounds in its class, the molecular weight of 582.85 g/mol gives DIADINOXANTHIN distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
DIADINOXANTHIN (CAS 18457-54-0), molecular formula C40H54O3 and molecular weight 582.85 g/mol, is a CATO reference standard with documented purity and traceability.
DIADINOXANTHIN (C40H54O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
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.
