DIBENZ(A,H)ACRIDINE Usage And Synthesis

Chemical Properties

Yellow Crystalline Solid

Uses

A urinary metabolite from inhalation and dermal exposure to polycyclic aromatics hydrocarbons in hot mix asphalt paving workers. A heterocyclic aromatic compound with potent mutagenic and carcinogenic properties.One of the azaarenes found in grilled meat.

Definition

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

General Description

Yellow crystals. Insoluble in water.

Air & Water Reactions

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

Reactivity Profile

DIBENZ(A,H)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. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also ANTHRACENE.
