Benzo[a]pyrene-7,8-dione is a metabolite of the widespread carcinogen benzo[a]pyrene. It has a role as a xenobiotic metabolite and a genotoxin. It is a member of pyrenes and a member of orthoquinones. It is functionally related to a benzo[a]pyrene-cis-7,8-dihydrodiol. It derives from a hydride of a benzo[a]pyrene."}]
