Used as a flame retardant in various industrial applications, particularly in plastics, textiles, and electronic enclosures to reduce flammability. It helps prevent the spread of fire by interfering with the combustion process. Commonly incorporated into polymers during manufacturing to meet fire safety standards. Also found in some adhesives and coatings where fire resistance is required. Additionally, it serves as an intermediate in the synthesis of more complex flame retardants. Its use has declined in some regions due to environmental and health concerns related to persistence and bioaccumulation.
