2,6-Naphthalenedicarboxylic acid（Cat No.:R053868）is an aromatic dicarboxylic acid featuring carboxyl groups at the 2 and 6 positions of the naphthalene ring. This rigid, planar molecule serves as a key monomer in the synthesis of high-performance polyesters and polyamides, such as polyethylene naphthalate (PEN), offering improved thermal stability, mechanical strength, and gas barrier properties over PET. It is valued in materials science for producing specialty plastics, resins, and films. Its symmetrical structure also makes it useful in the design of liquid crystalline polymers and advanced functional materials for electronics and packaging.
