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]
