Chemical Structure
Description
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Diethyl (4-(trifluoromethyl)benzyl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Diethyl (4-(trifluoromethyl)benzyl)phosphonate (CAS 99578-68-4) is a high-purity analytical reference standard with the molecular formula C12H16F3O3P and a molecular weight of 296.22 g/mol.
