Opis

Opis ogólny

Sodium hypophosphite, also known as sodium phosphinate, is a sodium salt of hypophosphorous acid. It is used as a reducing agent for the reduction of metal salts to metals in an aqueous solution. It is also employed as a source of hydrogen in heterogeneous catalytic transfer reductions.
