Dibenzo-p-dioxin (dibenzo-para-dioxin) or dibenzo-14-dioxin is a polycyclic heterocyclic organic compound in which two benzene rings are connected by a 14-dioxin ring. Its molecular formula is C12H8O2. The two oxygen atoms occupy opposite (para-) positions in the six-membered dioxin ring.Dibenzodioxin is the carbon skeleton of the poisonous polychlorinated dibenzodioxins (PCDDs) often called dioxins. The most harmful PCDD is 2378-tetrachlorodibenzodioxin (TCDD).
