Hypophosphorous acid 50% - H3PO2 (CAS: 6303-21-5)
Hypophosphorous acid 50% an ionic compound that can be synthesized by reacting boric acid Intermediates hydrofluoric acid Intermediates then adding additive hydroxide. The most general method to prepare hypophosphorous acid is by hydrolysis of dialkyl phosphonate to phosphonic acid with concentrated HCl solution.
Hypophosphorous acid is used as a bleaching or decolorizing agent for plastics, synthetic fibres, and chemicals and also as a colour stabilizer and decolourizing agent in the manufacture of several plastics and chemicals. In electroplating it is used as a wetting, emulsifying or dispersing agent. The substance is used as an acidifying compound, chemical reducer, anti-oxidant, catalyst, in synthesis and electroless nickel plating and as a polishing agent.

Hypophosphorous Acid (HPA) also known as phosphinic acid is a colorless low-melting compound,it is used in applications like; as catalyst during esterification alkyd synthesis, reducing agent for electro less nickel plating, bleaching agent in synthetic fibers, color stabilizer during the manufacturing of chemicals and plastics and is also used in various organic chemistry applications. HPA serves as a neutralizing agent, antioxidant, catalyst in polymerization and poly condensation, and wetting agent. Further, it is used in the formulation of pharmaceuticals, discoloration of polymers, water treatment and retrieval of precious or non-ferrous metals.
