A benzopyrene is an organic compound with the formula C20H12. Structurally, these colourless pentacyclic hydrocarbon are related to pyrene ring by fusion of phenylene group. Two isomeric species are benzo[a]pyrene and the less common benzo[e]pyrene. Related compounds include cyclopentapyrenes, dibenzopyrenes, indenopyrenes and naphthopyrenes.
Benzopyrene is a component of pitch. Related pentacyclic aromatic species include picene, benzofluoranthenes, and perylene.[1] Benzopyrenes are problematic because they intercalate into DNA, interfering with transcription. It is considered a pollutant and carcinogen.
It can be found in coal tar (after forest fire), after eruption of volcanoes and in cigarette smoke.
