664-03-9 Usage
General Description
1-Bromo-2,3,4-trichloro-1,1,2-trifluorobutane, also known as Halon 1301, is a chemical compound that was commonly used as a fire-extinguishing agent in the past. It is a member of the halogenated hydrocarbon family and is highly effective at suppressing fires by interrupting the chemical reaction that sustains combustion. However, due to its ozone-depleting properties, its use has been largely discontinued since the 1990s. Exposure to 1-Bromo-2,3,4-trichloro-1,1,2-trifluorobutane can result in respiratory issues, skin irritation, and central nervous system effects. It is considered hazardous to the environment and human health, and its production and use are regulated under international agreements such as the Montreal Protocol.
