Quick Summary

Dimethyl trichlorophenyl phosphorothioate is a chemical compound derived from 2,4,5-trichlorophenol. It is a systemic agent used to control grubs in cattle. This compound is an organophosphate, a class of chemicals related to nerve gases, and is known for its toxicity to vertebrates, including humans.12

The synthesis of this compound involves 2,4,5-trichlorophenol, which can be produced by treating phenol with chlorine. Phosphorus trichloride (PCl₃) is a volatile liquid used in the creation of organic phosphorus compounds. While not directly related to the synthesis of dimethyl trichlorophenyl phosphorothioate, other organophosphates like phorate are potent pesticides that inhibit cholinesterases, enzymes crucial for nerve impulse transmission.132
