Used primarily as a solvent and intermediate in organic synthesis, particularly in the production of other brominated compounds. It is also employed in the manufacturing of flame retardants, which are critical in enhancing the fire resistance of materials such as plastics, textiles, and electronics. In laboratory settings, it serves as a heavy liquid for mineral separation and density determination. Additionally, it has been utilized in the past as a component in certain types of gauging fluids and in the synthesis of pharmaceuticals and agrochemicals. Due to its high density, it finds niche applications in geological and industrial processes where precise density measurements are required. However, its use is limited and regulated due to environmental and health concerns associated with brominated compounds.
