Description and Uses

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.

There is no report on the common use of dibenz[a,h]anthracene and its commercial production.
