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.

When combined with hexamine and compressed into solid bars, it is used by the military and outdoorsmen as a cooking fuel which is commonly known as Esbit.

The only possible mono-bromo derivative of trioxane is C₃H₅BrO₃
