Bromomethane

Bromomethane, also known as methyl bromide, is a bromine-containing organic compound. It is colorless, odorless, nonflammable, and volatile.

Chemical Properties

Bromomethane is a haloalkane with the chemical formula CH3Br. It is a dense, colorless, slightly sweet-smelling liquid or gas. At room temperature, it is volatile; therefore, its gas is heavier than air. Bromomethane is soluble in organic solvents but only slightly soluble in water.

Production and Uses

Bromomethane is produced by the bromination of methane, which is a radical substitution reaction. It is primarily used as a fumigant and pesticide. It is also used in fire extinguishers, refrigeration systems, and as a precursor in the manufacture of other chemicals.

Health Effects

Exposure to bromomethane can lead to serious health effects. It is a potent neurotoxin, and inhalation can cause headache, dizziness, confusion, and, at high concentrations, seizures or even death. Chronic exposure can lead to neurological damage and impairment of the central nervous system.

Environmental Impact

Bromomethane is a significant ozone-depleting substance. It is also a potent greenhouse gas. Its use is restricted under the Montreal Protocol, an international treaty designed to protect the ozone layer.
