Chlorfenvinphos is an organophosphorus compound that was widely used as an insecticide but has been banned in several countries. It is a colorless solid, but for commercial purposes, it was marketed as an amber liquid. Its use in the U.S. was cancelled in 1991. Chlorfenvinphos was sold under several brand names.

The molecule can be described as an enol ester derived from dichloroacetophenone and diethylphosphonic acid. The molecule hydroyzes in the environment.

Safety

The substance has harmful effects on the nervous system. The LD₅₀ is 15  mg/kg (rats, oral).
