Used primarily as a laboratory reagent in organic synthesis, particularly in the preparation of other halogenated compounds. It serves as a brominating agent in certain chemical reactions where controlled bromine transfer is required. Also employed in research settings for studying reaction mechanisms involving free radicals due to its ability to generate bromine radicals under specific conditions. Historically, it was used in small amounts in industrial processes as a solvent or intermediate, though such uses have declined due to environmental and toxicity concerns. Its application is now mostly limited to specialized chemical research.
