Description: Hypophosphorous acid (HPA), also known as phosphinic acid, is a phosphorus oxyacid and a strong reducing agent, with the molecular formula H₃PO₂. It is a colorless compound with a low melting point, available as deliquescent crystals or an oily liquid, and is soluble in water, dioxane, and alcohols. HPA has many applications: – Reducing agent. – Antioxidants. – Catalysts. – Color stabilizers. – Surfactant. Standards: Hypophosphorous acid concentration: 50 – 52% pH: 1.4 Shelf-life: 3 years Applications: HPA 50 % is used as a stabilizer system, buffer solution, pH regulator in pharmaceutical products, Calcium supplementation drinking products; and as antioxidants agent. Color stabilizers for chemicals and plastics. Used in production of Hypophosphite Salts (Calcium, Magnesium, Manganese, Potassium, Iron, and Ammonium) which are used in synthetic fibers as wetting dispersing, emulsifying, and anti-static agents. Chemical intermediate: used in organic synthesis and phosphinic acid production. Catalyst, neutralizing agent, antioxidants. Wetting agent, dispersing agent, emulsifiers in electroplating.
