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.
