Sodium Hypophosphite is used in formulating many pharmaceutical products. It is a common reducing agent for metal plating. It is a critical ingredient of electroless nickel plating solutions. It is used as a water treatment agent and as a meat preservative. It is used to prevent the discoloration of polymers. It is used to manufacture hypophosphorous acid which has same application with Sodium Hypophosphite. (But hypophosphorous acid has an advantage of easy implementation in solution.).
