[{"from": "human", "value": "Describe this molecule. [C][=C][Br]"}, {"from": "gpt", "value": "The molecule is a colorless, highly flammable gas of brominated hydrocarbon, with a characteristic pungent odor. Bromoethene is mainly used in the production of polymers and copolymers for rubber, plastic, leather and fabricated metal production. Exposure to bromoethene causes dizziness, disorientation, sleepiness. Chronic exposure causes liver and kidney damage. Its metabolites, via cytochrome P450 oxidation, are potent alkylating agents and causes DNA adducts, which is responsible for the carcinogenic effect. Bromoethene is reasonably anticipated to be a human carcinogen. (NCI05)"}]
