CFBr

CFBr, also known as carbon tetrabromide, is a chemical compound with the formula CBr4. It is a colorless, crystalline solid with a camphor-like odor. CFBr is a haloalkane, specifically a halomethane, where carbon is bonded to four bromine atoms.

CFBr is practically insoluble in water but is soluble in many organic solvents such as ethanol, ether, and chloroform. It is a dense compound, with a melting point of approximately 92-94 degrees Celsius and a boiling point of around 190 degrees Celsius. Due to its high density, it has been used as a component in density separation techniques.

Historically, CFBr found some use as a fire suppressant due to its ability to interrupt the combustion chain reaction. However, concerns about its ozone-depleting potential, similar to other halons, have led to its phase-out in many applications. It has also been explored in organic synthesis as a brominating agent.

In the laboratory, CFBr can be synthesized through various methods, including the reaction of carbon disulfide with bromine or the reaction of bromoform with bromine under specific conditions. It is considered a relatively stable compound under normal conditions but can decompose when exposed to heat or light, releasing toxic fumes of bromine. Environmental regulations and its potential hazards have significantly limited its commercial production and use.
