Hypo Phosphorous acid Application/Usage

 

Hypo Phosphorous acid may be used as Reducing Agent for its strong but slow reducing action, and be used in the production 

of Hypophosphite Salts (i.e., Calcium, Magnesium, Manganese, Potassium, Iron, and Ammonium) which are in turn used in 

synthetic fibers as wetting dispersing, emulsifying, and anti-static agents.

 

Hypo Phosphorous acid also can be used as Bleaching AgentColor StabilizerChemical IntermediateNeturalizing Agent

Wetting AgentAntioxidant or as a stimulant in pharmaceuticals.
