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.[5]
- CH3-N=N-CH3 → 2 CH3· + N2
