tribromoethane

Tribromoethane, also known as bromoform or methyl tribromide, is a halogenated hydrocarbon with the chemical formula CHBr3. It is a clear, dense liquid with a sweet odor, though its vapors can be irritating. Tribromoethane is a volatile organic compound and is heavier than water.

Historically, tribromoethane was used as a sedative and anesthetic, but its use was discontinued due to toxicity concerns, particularly its effects on the liver and kidneys. It is also known to be a potential carcinogen. Currently, its primary applications are in laboratory settings as a solvent for fats, oils, and waxes, and as a reagent in organic synthesis. It has also been used in the past as a fire suppressant, though more effective and less toxic alternatives are now widely available.

Tribromoethane can be synthesized through various methods, including the haloform reaction. This reaction typically involves reacting a methyl ketone or a secondary alcohol that can be oxidized to a methyl ketone with a halogen in the presence of a base.

Exposure to tribromoethane can occur through inhalation, skin contact, or ingestion. Symptoms of exposure can range from dizziness and headaches to more severe effects such as liver damage, respiratory distress, and central nervous system depression. Due to its toxicity, proper handling procedures, including adequate ventilation and personal protective equipment, are essential when working with tribromoethane. Environmental concerns also exist, as it is a persistent organic pollutant and can contribute to ozone depletion.
