Hypophosphorous Acid, molecular formula:- H3PO2, is a colourless phosphorus oxo-acid compound. Hypophosphorous Acid is act as a strong reducing agents. Generally, production of conventional hypophosphorous acid is carried out by a metathesis method or an ion exchange resin method. Hypophosphorous Acid is stable compound under normal condition, however, after heating it decomposes into phosphoric acid, hydrogen and phosphine compound. Generally, Hypophosphorous Acid are used as bleaching agent in synthetic fibers, plastics, and chemicals applications. Also, hypophosphorous acid and its derivative compounds i.e. hypophosphite salts such as calcium hypophosphite, magnesium hypophosphite, and sodium hypophosphite, among others, are prevalently used in synthesis of chemicals, pharmaceuticals, electroplating, and water treatments applications. Also, Hypophosphorous Acid is used as a decolorizing agent and stabilising agent in production of polymer and plastic compounds such as polyamides, nylon fibers, alkyd resins, polyacrilonitrile, polyester fibre, epoxies, and fatty acid esters, among others.
