Application

1.Triphenylphotosphine is widely used in industries such as pharmaceuticals, petrochemicals, coatings, rubber, etc. It can be used as stabilizer for synthetic rubber and resins, brightener for dye processes, antioxidant for polymer polymerization, color film imaging, stabilizer for polyepoxidation, and also as analytical reagent.

2.Triphenylphosphine is also used as polymerization initiator and as raw material for antibiotics such as chloramphenicol.

3.In pesticides, Triphenylphosphine is used to synthesize the organic phosphorus intermediate trimethyl phosphite, which can then yield a series of organic phosphorus insecticides such as dichlorvos, monocrotophos, and phosphoramide.
