Oxirane is a saturated organic heteromonocyclic parent that is a three-membered heterocycle of two carbon atoms and one oxygen atom. It has a role as a mutagen, an allergen and a mouse metabolite. Ethylene oxide appears as a clear colorless gas with an ethereal odor with a flash point below 0 °F. Liquid less dense than water. Vapors heavier than air.
