1,3,5-Trioxane is a stable cyclic trimer of formaldehyde with a chloroform-like odor. Being a trioxane, it has the molecular formula C3H6O3 and consists of a six membered ring with three carbon atoms and three oxygen atoms.
In chemistry, it is used as a stable, easily handled source of anhydrous formaldehyde. In acidic solutions, it decomposes to generate three molecules of formaldehyde. It may also be used in polymerization to form acetal resins, such as polyoxymethylene.
Trioxane is also occasionally known by the synonym trioxin, sometimes mistaken for the fictional 2,4,5-trioxin.
The only possible mono-bromo derivative of trioxane is C3H5BrO3.
