Structures and Environmental Significance of Heptachlor Epoxide Isomers

Journal of AOAC INTERNATIONAL, 1993
Abstract Historically, both endo- and exo-epoxides of heptachlor are known. The exo-epoxy isomer of heptachlor epoxide is a remarkably stable metabolite of heptachlor and is generally found in the environment where heptachlor was introduced.
