Used primarily as a solvent in organic synthesis and in the preparation of other bromine-containing compounds. It serves as an intermediate in the production of flame retardants and agricultural chemicals. Historically used in fire extinguishers and as a general anesthetic, though these applications have been discontinued due to toxicity concerns. Occasionally employed in laboratory settings for bromination reactions and as a heavy liquid in mineral separation techniques. Its use is limited today because of environmental and health risks associated with brominated hydrocarbons.
