Bromotrifluoromethane

Bromotrifluoromethane is a halomethane that is commonly used as a fire extinguishing agent. It is a colorless, nonflammable liquid that is heavier than air and has a sweet odor. It is also known by its IUPAC name, trifluoromethyl bromide, and its Chemical Abstracts Service (CAS) number, 75-63-8.

Chemical Properties

Bromotrifluoromethane has a molecular formula of CBrF3 and a molar mass of 148.91 g/mol. It is a halogenated hydrocarbon that is composed of one carbon atom, one bromine atom, and three fluorine atoms. It is a volatile liquid at room temperature and has a boiling point of 23.6°C (74.5°F).

Uses

Bromotrifluoromethane is primarily used as a fire extinguishing agent. It is effective in suppressing fires in enclosed spaces, such as in aircraft, ships, and computer rooms. It is also used in the production of semiconductors and as a refrigerant in some applications.

Health Effects

Exposure to bromotrifluoromethane can cause central nervous system depression, resulting in dizziness, headache, confusion, and at high concentrations, unconsciousness and death. It can also cause cardiac arrhythmia if inhaled in high concentrations.

Environmental Impact

Bromotrifluoromethane is a potent greenhouse gas with a global warming potential approximately 5,000 times that of carbon dioxide. It also contributes to the depletion of the ozone layer.
