Description
(4AR,11bS)-11b-benzyl-4a-methyl-3-oxo-2,3,4,4a,5,6,7,11b-octahydro-1H-dibenzo[a,c][7]annulen-9-yl trifluoromethanesulfonate (CAS 1958063-31-4), molecular formula C24H25F3O4S and molecular weight 466.51 g/mol, is a CATO reference standard with documented purity and traceability.
(4AR,11bS)-11b-benzyl-4a-methyl-3-oxo-2,3,4,4a,5,6,7,11b-octahydro-1H-dibenzo[a,c][7]annulen-9-yl trifluoromethanesulfonate (C24H25F3O4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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.
