(1) Raw materials used as intermediates for liquid crystal polymers. (2) In terms of synthetic polymers, due to their heat resistance*, they are used as modified monomers of polyesters, polyurethanes, polycarbonate, polysupon and epoxy resins to manufacture excellent engineering plastics and composites. (3) It is used as a rubber anti-aging agent and plastic antioxidant. (4) Stabilizers for dye intermediates or petroleum products.

This product can be used as an important organic intermediate of engineering plastics, organic pigments, liquid crystal materials and medicine, especially as a monomer of temperature-resistant synthetic materials.

This product can be used as a preservative, dye, pharmaceutical and injection molding intermediate, and alcohol esterification can be obtained. It is also the main raw material of polymer liquid crystal polymer and the raw material of pesticide intermediate.
