Dibenz[a,h]anthracene is an organic compound with the chemical formula C22H14. It is a polycyclic aromatic hydrocarbon made of five fused benzene rings. It is a fused five ringed, cyclopenta, PAHs compound which is common as a pollutant of smoke and oils. It is white to light yellow crystalline solid. It is stable and highly genotoxic in bacterial and mammalian cell systems, as it intercalates into DNA and causes mutations.

More than 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life. PAHs seem to have been formed shortly after the Big Bang, are widespread throughout the universe, and are associated with new stars and exoplanets.[1]
