Description
(-)-(((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(bis(3,5-bis(trifluoromethyl)phenyl)phosphane)-rel (CAS 220196-30-5), molecular formula C39H24F24O2P2 and molecular weight 1042.52 g/mol, is a CATO reference standard with documented purity and traceability.
(-)-(((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(bis(3,5-bis(trifluoromethyl)phenyl)phosphane)-rel (C39H24F24O2P2) contains organophosphorus functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
