[{"from": "human", "value": "Could you give me a brief overview of this molecule? [C][=Branch1][=Branch1][=C][Branch1][C][Cl][Cl][Cl]"}, {"from": "gpt", "value": "The molecule is a synthetic, light sensitive, volatile, colorless, liquid that is miscible with many non-polar organic solvents. Trichloroethylene is used mainly as a degreaser for metal parts. Upon combustion, it produces irritants and toxic gases. Occupational exposure to trichloroethylene is associated with excess incidences of liver cancer, kidney cancer and non-Hodgkin lymphoma. It is reasonably anticipated to be a human carcinogen.
