Methyl hypochlorite is the simplest of the organic alkyl hypochlorites. It is an explosively unstable and highly toxic compound that can be produced by the reaction of methanol with hypochlorous acid.[1] It was first synthesized by Sandmeyer in the 1880s.[2]

Methyl hypochlorite can form in the Earth's atmosphere by a reaction between ClO and CH3OO and is thought to be an important species in ozone destruction over the Artic and Antarctic regions.[3]
