Azomethane is an organic compound with the chemical formula CH3-N=N-CH3.

It exhibits cis-trans isomerism.

It can be produced by the reaction of 1,2-dimethylhydrazine dihydrochloride with copper(II) chloride in sodium acetate solution.

The reaction produces the azomethane complex of copper(I) chloride, which can produce free azomethane by thermal decomposition.

[4] It is the source of methyl radical in laboratory.
