Chlorine peroxide (also known as dichlorine dioxide or ClO dimer) is a molecular compound with formula ClOOCl.^[1] Chemically, it is a dimer of the chlorine monoxide radical (ClO·). It is important in the formation of the ozone hole.^[2] Chlorine peroxide catalytically converts ozone into oxygen when it is irradiated by ultraviolet light.^[3]
