Raw material used as an intermediate for liquid crystal polymers. In synthetic polymers, used as a modified monomer for polyesters, polyurethanes, polycarbonate, polysulfone, and epoxy resins to manufacture engineering plastics and composites due to its heat resistance. Also used as a rubber anti-aging agent, plastic antioxidant, and stabilizer for dye intermediates or petroleum products.
