Used primarily as a flame retardant in industrial applications, especially in electrical equipment, plastics, and textiles due to its ability to inhibit combustion. Its high bromine content enhances thermal stability, making it effective in preventing fire spread in polymers such as polyolefins and polystyrene. Also found in older formulations for circuit boards and insulation materials. Due to environmental persistence and toxicity concerns, its use has been largely phased out in many countries.
