Description and Uses
Like pure heptachlor, heptachlor epoxide is awhite powder that does not explode easily. Heptachlor epox-ide is an oxidation product of heptachlor formed by plantsand animals, including humans, after exposure to heptachlor.About 20% of heptachlor is changed within hours intoheptachlor epoxide in the environment and in the body. It isalso present as acontaminant in heptachlor. It was notmanufactured and was not usedas an insecticide likeheptachlor. Molecular weight = 389.30; Freezing/Meltingpoint= 160- 162℃. Hazard Identification (based on NFPA-704 M Rating System): Health 3, Flammability 1, Reactivity0. Soluble in water.
The cis-metabolite of organochlorine pesticide Heptachlor.
