Dibenz[a,h]anthracene Chemical Properties,Uses,Production


1, 2:5, 6-DIBENZANTHRACENE is a crystalline aromatic hydrocarbon. It is a component of coal tars, shale oils, and soots (IARC, 1985) and has been detected in gasoline engine exhaust, coke oven emissions, cigarette smoke, charcoal broiled meats, vegetation near heavily traveled roads, and surface water and soils near hazardous waste sites. It is a kind of carcinogenic compound, and thus being mainly used for the research purpose. For example, in biological research, it is a mutagen used to induce tumorigenesis.

Chemical Properties

white to light yellow crystalline solid


Dibenz[a,h]anthracene is a polycyclic aromatic hydrocarbon (PAH) and a known carcinogen. Dibenz[a,h]anthracene has produced positive results in bacterial DNA damage and mutagenicity assays and in mammalian cell DNA damage, mutagenicity and cell transformation assays.

General Description

White crystals or pale yellow solid. Sublimes.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

1,2:5,6-DIBENZANTHRACENE is incompatible with strong oxidizing agents. Is oxidized by chromic acid and by osmium tetraoxide .

Fire Hazard

Flash point data for 1,2:5,6-DIBENZANTHRACENE are not available; however, 1,2:5,6-DIBENZANTHRACENE is probably combustible.
