(R)-8,8'-Bis(3,5-bis(trifluoromethyl)phenyl)-2,2',3,3'-tetrahydro-1,1'-spirobi[phenalene]-9,9'-diol (CAS 2687968-84-7), molecular formula C41H24F12O2 and molecular weight 776.61 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-8,8'-Bis(3,5-bis(trifluoromethyl)phenyl)-2,2',3,3'-tetrahydro-1,1'-spirobi[phenalene]-9,9'-diol (C41H24F12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. 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).
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.
