Sodium Hypophosphite Monohydrate Fine Crystals 99.9% Purity

Sodium Hypophosphite is primarily used as a reducing agent in electroless nickel plating (Ni-P), where it reduces nickel ions in solution to metallic nickel, forming a durable, uniform nickel-phosphorus film on both metal and non-metal substrates like plastics, ceramics, and glass. This process is especially valuable for coating complex shapes, large equipment, and internal surfaces of deep hollows, providing excellent surface hardness and abrasion resistance, and is widely applied in electronics, aviation, machinery, and the petroleum industry.

Beyond plating, sodium hypophosphite serves as a chemical intermediate, notably in the production of hypophosphorous acid. It acts as a polymerization catalyst and a stabilizer to prevent polymer degradation during extrusion and other thermal processing. It is also used as a flame retardant, an antioxidant, and a preservative in various applications.

In the food industry, sodium hypophosphite is used as a food additive, functioning as an antioxidant, leavening agent, emulsifier, and stabilizer, and is considered Generally Recognized As Safe (GRAS). It can be used in meat products, dairy, baked goods, and as a preservative to extend shelf life. It also has applications in pharmaceuticals, where it can act as a buffer or controlled release agent.

Other uses include water treatment, where it reduces metal ion content in industrial wastewater and prevents scaling in pipelines, particularly in hot water systems and oil fields. It is employed in concrete admixtures to improve drying rate and firmness, and in textile finishing as an antioxidant and anti-discoloration agent. Additionally, it functions as an analytical reagent and a catalyst in synthetic organic chemistry, such as in the deamination of diazo derivatives.
