[{"from": "human", "value": "Could you give me a brief overview of this molecule? [C][Branch1][C][Cl][Branch1][C][Cl][Cl]"}, {"from": "gpt", "value": "The molecule is a colorless, volatile, liquid derivative of trichloromethane with an ether-like odor.  Formerly used as an inhaled anesthetic during surgery, the primary use of chloroform today is in industry, where it is used as a solvent and in the production of the refrigerant freon.  Acute chloroform toxicity results in impaired liver function, cardiac arrhythmia, nausea and central nervous system dysfunction.  As a byproduct of water chlorination, chloroform may be present in small amounts in chlorinated water. (NCI04)"}]
