The molecule is an organochlorine compound resulting from the Diels-Alder reaction of hexachlorocyclopentadiene with norbornadiene. A proinsecticide (by epoxidation of the non-chlorinated double bond to give dieldrin), it was widely used as an insecticide before being banned in the 1970s as a persistent organic pollutant. It has a role as a persistent organic pollutant and a proinsecticide. It is an organochlorine insecticide and an organochlorine compound.
