[C][N][N][C]"}, {"from": "gpt", "value": "The molecule is a compound used experimentally to induce tumors in animal models of carcinogenesis.  In mice and rats, 1,2-dimethylhydrazine may induce carcinogenesis through deregulation of the cell cycle. This agent primarily induces gastrointestinal and vascular tumors. 1,2-Dimethylhydrazine may be found in small amounts in the environment due to its use in industry and agriculture. (NCI04)"}]
