Usage

General Description

1-bromo-1,1-difluoro-ethane, also known as Halon 1211, is a colorless, non-flammable chemical compound with the chemical formula C2H3BrF2. It is primarily used as a fire-extinguishing agent in portable fire extinguishers and some firefighting equipment due to its ability to extinguish a wide range of fires, particularly those involving flammable liquids and electrical equipment. However, it is also a potent ozone-depleting substance and has been largely phased out of use in many countries due to its environmental impact. Its use is heavily restricted and regulated under the Montreal Protocol and other international agreements. In addition to its fire-fighting applications, it is also sometimes used as a solvent in organic synthesis.
