Phosphorous acid is an intermediate in the preparation of other phosphorous compounds.

It is a raw material to prepare phosphonates for water treatment such as iron and manganese control,

scale inhibition and removal, corrosion control and chlorine stabilization.

Phosphorous acid is used in stabilizing mixtures for plastic materials.

Phosphorous acid is used for inhibiting high-temperature of corrosion-prone metal surfaces and to produce lubricants and lubricant additives.

Phosphorous acid is used to produce the fertilizer phosphate salt like potassium phosphite, ammonium phosphite and calcium phosphite.
