Application

1,4-Cyclohexanedicarboxylic acid is widely used as a monomer in the production of thermoplastic polyesters (e.g., PCT) for engineering plastics and fibers. It serves as a precursor for corrosion-resistant coatings and adhesives due to its stability under harsh conditions. In pharmaceuticals, it acts as an intermediate for drug candidates targeting metabolic disorders. Its rigid structure also makes it valuable in liquid crystal displays (LCDs) and high-temperature composites.
