[{"from": "human", "value": "Provide a description of this molecule. [C][Br]"}, {"from": "gpt", "value": "The molecule is an organobromide compound that may be produced both synthetically and by naturally marine organisms and certain terrestrial plants. It was used extensively as a pesticide and as a fire extinguisher component until being phased out by most countries in the early 2000s, as it is considered an ozone-depleting substance. The primary use of methyl bromide is/was as a fumigant in soil to control fungi, nematodes, and weeds; in space fumigation of food commodities (e.g., grains); and in storage facilities (such as mills, warehouses, vaults, ships, and freight cars) to control insects and rodents. Its popularity as a fumigant is largely attributable to its high toxicity to many pests, the variety of settings in which it can be applied, its ability to penetrate the fumigated substances, and its rapid dissipation following application. Trace amounts of methyl bromide have been detected in drinking water.  There are many reports of humans who have died following acute inhalation exposure to bromomethane. Most cases have involved accidental exposures associated with manufacturing or packaging operations, use of fire extinguishers containing bromomethane, or fumigation activities. Death is not immediate, but usually occurs within l-2 days of exposure. The cause of death is not certain, but is probably due to neurological and lung injury."}]
