It is used in organic synthesis, and also used as a raw material for polymerization initiators, antibiotic drugs, such as clindamycin
In pesticides, it can be used to synthesize organophosphorus intermediate trimethyl phosphite by transesterification, and then a series of organophosphorus pesticides such as dichlorvos, monocrotophos and phosphoramine can be obtained. In addition, it can be used as synthetic rubber and resin. Stabilizer, antioxidant of polyvinyl chloride, used as raw material for synthesizing alkyd resin and polyester resin.
It is used for organic synthesis, polymerization initiator, raw material of antibiotic drug clindamycin, and standard sample for determination of phosphorus in organic trace analysis.
It should be kept dry during storage, and the temperature should be above 10 ℃. Crystals are precipitated below 10 °C, and the use effect will not be affected after heating and melting.
