Phosphonic and Phosphinic Acids

Series of phosphonic and phosphinic acids and their derivatives

Phosphinic acid is a phosphorus oxyacid (monoprotic acid) and is also called hypophosphorous acid (H3PO2). It is a powerful reducing agent and therefore, is used for the reduction of arenediazonium salts. It is also used for electroless nickel plating in industries.  Phosphonic acids are organic derivatives of phosphorus acid with general formula RPO3H2. They are diprotic acids and are mostly used for the synthesis of basic lead phosphite, a stabilizer in PVC and other chlorinated polymers. They are known as effective chelating agents.
