The chemical substance 1,2-dioxetane (systematically named 1,2-dioxacyclobutane, also known as ethylene peroxide or peroxyethane) is a heterocyclic, organic compound with formula C₂O₂H₄, containing a ring of two adjacent oxygen atoms and two adjacent carbon atoms. It is therefore an organic peroxide, and can be viewed as a dimer of formaldehyde (COH₂).
