LIGHT YELLOW TO BROWN POWDER

The Uses of 1,2:3,4-DIBENZANTHRACENE

Dibenzo[a,c]anthracene is a polycyclic aromatic hydrocarbon which are known carcinogens and environmental pollutants.

Definition

ChEBI: Dibenz[a,c]anthracene is a carbopolycyclic compound.

Safety Profile

Questionable carcinogen withexperimental tumorigenic data. Human mutation datareported. When heated to decomposition it emits acridsmoke and irritating fumes.

Carcinogenicity

Dibenz[a,c]anthracene was administered dermally to mice, either per se or as part of initiation–promotion protocols. The working group concluded that there was limited evidence for animal carcinogenicity. In later studies on an initiation–promotion study on mouse skin, low initiating doses gave negative results when administered subcutaneously to mice, and tumor incidence was not significantly increased over that observed in controls when the compound was administered intraperitoneally to newborn mice.
