Dibenzo-p-dioxin Chemical Properties, Uses, Production

Chemical Properties

white crystalline solid

Uses

Dibenzo-p-dioxin is a standard used in environmental testing and research as well as in the studying of PCBs, PCDDs and PCDFs in food.

Definition

ChEBI: Oxanthrene is a heteranthrene, a mancude organic heterotricyclic parent, a polycyclic heteroarene, an oxacycle and a dibenzodioxine.

Synthesis Reference(s)

General Description

White crystals or crystalline solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

DIBENZO-P-DIOXIN is an ether. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

Fire Hazard

Flash point data for DIBENZO-P-DIOXIN are not available. DIBENZO-P-DIOXIN is probably combustible.
