200px|thumb|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.

==Isomers== The three isomers are: 1,2,3-trioxane, a hypothetical compound that is the parent structure of the molozonides 1,2,4-trioxane, a hypothetical compound whose skeleton occurs as a structural component of some antimalarial agents (artemisinin and similar drugs) 1,3,5-trioxane, a trimer of formaldehyde used as fuel and in plastics manufacturing, and also as a solid fuel tablet when combined with hexamine
