DIBENZ(A,J)ACRIDINE Usage And Synthesis

Chemical Properties

Light Green Solid

Uses

A heterocyclic aromatic compound with potent mutagenic and carcinogenic properties

Definition

ChEBI: Dibenz[a,j]acridine is an organonitrogen heterocyclic compound and a polycyclic heteroarene.

Synthesis Reference(s)

Journal of Heterocyclic Chemistry, 28, p. 139, 1991 DOI: 10.1002/jhet.5570280125

General Description

Yellow crystals.

Air & Water Reactions

Dust/air mixtures may ignite and explode. Insoluble in water.

Reactivity Profile

DIBENZ(A,J)ACRIDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also ANTHRACENE.
