Trimethyl thiophosphate

CAS: 152-18-1

Trimethyl thiophosphate is a white solid that is soluble in organic solvents. It is used as an intermediate in the production of pesticides and other industrial chemicals, such as phosphites and thiophosphates. Trimethyl thiophosphate can be synthesized by reacting phosphorus pentasulfide with trimethylamine. The reaction products are trimethyl phosphate, dimethyl phosphite, and sulfuryl chloride. Trimethyl thiophosphate has been shown to cause kidney fibrosis in mice when it was injected into the kidney at a dose of 3 mg/kg body weight. This chemical also may have some protective effects against metal surface corrosion due to its ability to form a protective film on the metal surface.
