The C2N2O core of<unk>  is planar, as established by X-ray crystallography. The central nitrogen is bound to two methyl groups and the NO group with bond angles of 120°. The N-N and N-O distances are 1.32 and 1.26 Å, respectively.<unk>  forms from a variety of dimethylamine-containing compounds, e.g. hydrolysis of dimethylformamide. Dimethylamine is susceptible to oxidation to unsymmetrical dimethylhydrazine, which air-oxidizes to<unk> . In the laboratory,<unk>  can be synthesised by the reaction of nitrous acid with dimethylamine: :HONO + (CH3)2NH → (CH3)2NNO + H2O The mechanism of its carcinogenicity involves metabolic activation steps resulting in the formation of methyl diazonium, an alkylating agent. Metabolic activation of<unk>  relevant to its cancer-causation.
