Sodium hypophosphite monohydrate can be used as a: Reducing agent in the synthesis of nickel
nanoparticles (NiNP) from nickel acetate tetrahydrate under microwave irradiation.
Sodium hypophosphite (NaPO2H2, also known as sodium phosphinate) is the sodium salt of hypophosphorous acid and is often encountered as the monohydrate, NaPO2H2·H2O. It is a solid at room temperature, appearing as odorless white crystals. It is soluble in water, and easily absorbs moisture from the air.
