Methyl hypochlorite
Methyl hypochlorite is the simplest of the organic alkyl hypochlorites. It is an unstable 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 forms 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 Arctic and Antarctic regions.[3]
