[C][Branch1][Ring1][C][Br][Br]"}, {"from": "gpt", "value": "The molecule is the organobromine compound with the chemical formula (CH2Br)2. Although trace amounts occur naturally in the ocean, where it is formed probably by algae and kelp, it is mainly synthetic. It is a colorless liquid with a sweet odor, detectable at 10 ppm, is a widely used and sometimes-controversial fumigant. The effects on people of breathing high levels are not known, but animal studies with short-term exposures to high levels caused depression and collapse, indicating effects on the brain."}]
