Trioxane

Trioxane isomers:1,2,3-trioxane (left), 1,2,4-trioxane (middle), and 1,3,5-trioxane (right)

Trioxane refers to any of three isomeric organic compounds composed of a six membered ring with three carbon atoms and three oxygen atoms, having the molecular formula C₃H₆O₃.

The three isomers are

1,2,3-Trioxane, a hypothetical compound related to molozonide^[1]
1,2,4-Trioxane, a hypothetical compound whose skeleton occurs as a structural element of some antimalarial agents (artemisinin and similar drugs).^[2]
1,3,5-Trioxane, a trimer of formaldehyde used as fuel and in plastics manufacture.
