Used primarily as a fire extinguishing agent in specialized fire suppression systems, especially in environments where water or conventional agents could cause damage, such as in electronic equipment rooms or aircraft. Its effectiveness comes from interrupting the chemical chain reaction of combustion. Also employed as a brominating agent in organic synthesis, facilitating the addition of bromine to various compounds in pharmaceutical and agrochemical manufacturing. Due to environmental concerns related to ozone depletion, its use has been largely phased out under international agreements, though it may still appear in limited, essential applications.
