Sodium Hypophosphite Monohydrate

We are Supplier, Exporter and Contract Manufacturer.

Sodium Hypophosphite Monohydrate is an inorganic reducing salt with the chemical formula H2NaO3P and molecular weight 105.99 g/mol. It appears as a white crystalline powder, highly soluble in water and stable under normal storage conditions when kept dry. It is non-flammable but decomposes on strong heating.
In terms of uses and applications, Sodium Hypophosphite Monohydrate is widely used as a reducing agent and is especially important in electroless nickel plating, where it serves as the reducing source for nickel deposition. It is also used in the chemical industry for producing hypophosphite salts, pharmaceuticals, and specialty phosphorus compounds. In polymer and textile industries, it acts as a catalyst and stabilizer. It is applied in water treatment, antioxidants, and laboratory synthesis. Additionally, it is used in flame retardant and resin formulations requiring phosphorus-based additives.
