Bis(perfluorophenyl)(phenyl)phosphineoxide (CAS 5594-90-1), molecular formula C18H5F10OP and molecular weight 458.19 g/mol, is a CATO reference standard with documented purity and traceability.
Bis(perfluorophenyl)(phenyl)phosphineoxide (C18H5F10OP) contains a steroid core, organophosphorus functionality, 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; 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.
