2,2',2'',5'-Tetrabromo-1,1':4',1''-terphenyl is primarily used as a flame retardant in various industrial applications. Its brominated structure makes it effective in reducing the flammability of materials, particularly in plastics, textiles, and electronic components. This compound is often incorporated into polymer matrices to enhance fire safety without significantly altering the material's physical properties. It is also utilized in the production of circuit boards and other electronic devices where flame resistance is critical to ensure safety and compliance with regulatory standards. Additionally, it may be employed in coatings and adhesives to improve their fire-resistant characteristics.
