What is DIBENZO(A,E)PYRENE?
The Uses of DIBENZO(A,E)PYRENE
Dibenzo[a,e]pyrene is a polyaromatic hydrocarbon with inherent carcinogenic properties.
Definition
ChEBI: Dibenzo[a,e]pyrene is an ortho- and peri-fused polycyclic arene.
General Description
Yellow crystals. Water insoluble.
Air & Water Reactions
Dust/air mixtures may ignite and explode. Insoluble in water.
Reactivity Profile
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DIBENZO(A,E)PYRENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
Safety Profile
Confirmed carcinogen with experimental neoplastigenic and tumorigenic data. When heated to decomposition it emits acrid smoke and irritating fumes.
Carcinogenicity
Dibenzo[a,e]pyrene was assessed in two initiation–promotion studies on mouse skin. One of the studies gave positive results while other gave negative results. Dibenzo[a,e]pyrene gave negative results when tested for carcinogenicity by intramamillary administration to rats.
