This chemical is primarily used as a flame retardant in various polymer systems, including epoxy resins and polyesters. Its ability to release bromine radicals during combustion helps to inhibit the spread of fire, making it valuable in applications where fire safety is critical, such as in electronics, construction materials, and automotive components. Additionally, it serves as an intermediate in organic synthesis, particularly in the production of specialized chemicals and pharmaceuticals. Its biphenyl structure contributes to its stability and effectiveness in high-temperature environments.
