Look up dioxin in Wiktionary, the free dictionary.
Dioxin may refer to a number of different substances. Most notably:
- 1,2-Dioxin or 1,4-Dioxin, two unsaturated heterocyclic 6-membered rings in which two carbon atoms have been replaced by oxygen atoms, which gives the molecular formula C4H4O2
- Dibenzo-1,4-dioxin, also known as dibenzodioxin or dibenzo-p-dioxin (molecular formula C12H8O2), in which two benzene rings are connected through two oxygen atoms. That is the parent compound of the dioxins (see next in which the dioxins comprise a key part of the class)
- Dioxins and dioxin-like compounds, a diverse class of chemical compounds that 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"
