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.[1]

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