((3AS,4R,6S,7R,7aS)-7-(benzoyloxy)-6-(ethylthio)-2,2-dimethyltetrahydro-4H-[1,3]dioxolo[4,5-c]pyran-4-yl)methyl benzoate (CAS 210093-48-4), molecular formula C25H28O7S and molecular weight 472.55 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((3AS,4R,6S,7R,7aS)-7-(benzoyloxy)-6-(ethylthio)-2,2-dimethyltetrahydro-4H-[1,3]dioxolo[4,5-c]pyran-4-yl)methyl benzoate (C25H28O7S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
