Methyl hypochlorite is an unstable and highly toxic compound that can be produced from reacting methanol with hypochlorous acid. It is extremely unstable and can decompose explosively giving off toxic fumes. Its instability is caused by the combination of the reducing methyl group and the oxidizing hypochlorite group.
