Bromoethane Manufacturer
Bromoethane is a manufactured chemical. It also occurs naturally in small amounts in the ocean where it is formed, probably by algae and kelp. It is a colorless, nonflammable gas with no distinct smell. Other names for bromoethane are methyl bromide, mono-bromoethane, and methyl fume. Trade names include Embafume and Terabol. Bromoethane is used to kill a variety of pests including rats, insects, and fungi. It is also used to make other chemicals or as a solvent to get oil out of nuts, seeds, and wool.
Methyl bromide appears as colorless highly toxic volatile liquid or a gas. Boiling point 3.56 °C (38.41 °F). Usually odorless, but has a sweetish chloroform-like odor at high concentrations. Used as an insecticide, a rodenticide, a fumigant, a nematocide, a chemical intermediate and as a fire extinguishing agent.
Bromoethane is a one-carbon compound in which the carbon is attached by single bonds to three hydrogen atoms and one bromine atom. It is produced naturally by marine algae. It has a role as a fumigant insecticide, a marine metabolite and an algal metabolite. It is a member of methyl halides, a member of bromoethanes and a bromohydrocarbon.
Methyl bromide is used as a fumigant and pesticide. Exposure may occur during fumigation activities. Methyl bromide is highly toxic. Studies in humans indicate that the lung may be severely injured by the acute (short-term) inhalation of methyl bromide. Acute and chronic (long-term) inhalation of methyl bromide can lead to neurological effects in humans. Neurological effects have also been reported in animals. Degenerative and proliferative lesions in the nasal cavity developed in rats chronically exposed to methyl bromide by inhalation. Chronic inhalation exposure of male animals has resulted in effects on the testes at high concentrations. EPA has classified methyl bromide as a Group D, not classifiable as to human carcinogenicity.
Bromoethane (or methyl bromide) 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; 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 bromoethane. Most cases have involved accidental exposures associated with manufacturing or packaging operations, use of fire extinguishers containing bromoethane, 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.
