WebPhosphoric acids and phosphates Pyrophosphoric acid. A phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron. Two or more of these PO WebPhosphoramidates are the aliphatic amides of phosphoric acid and are widely employed in the synthesis of differentially protected phosphate esters as more stable alternatives to halophosphates.88 They have been used as prodrug moieties to enhance water solubility 89 and to enhance the therapeutic potential of a parent drug. 90 In addition, they … shuffle club e1
