Description
CATO manufactures (diphenylphosphoryl)(4-fluorophenyl)methanol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(diphenylphosphoryl)(4-fluorophenyl)methanol (CAS 260446-45-5) is a high-purity analytical reference standard with the molecular formula C19H16FO2P and a molecular weight of 326.30 g/mol.
(diphenylphosphoryl)(4-fluorophenyl)methanol (C19H16FO2P) 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, 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.
