Dioxin

In chemistry, a dioxin is one of two unsaturated heterocyclic 6-membered rings where two carbon atoms have been replaced by oxygen atoms, giving the formula C₄H₄O₂:

• 1,2-Dioxin
• 1,4-Dioxin

Dioxin may refer to:

• Dioxins and dioxin-like compounds, a diverse range of chemical compounds which are known to exhibit “dioxin-like” toxicity
• 2,3,7,8-Tetrachlorodibenzodioxin (TCDD), the prototypical example of the above class, often referred to simply as "dioxin"
