Chemical Structure
Description
(4-(Trifluoromethyl)phenyl)phosphonic acid (C7H6F3O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(4-(Trifluoromethyl)phenyl)phosphonic acid (CAS 1869-27-8) is a high-purity analytical reference standard with the molecular formula C7H6F3O3P and a molecular weight of 226.09 g/mol.
