Terephthalic acid is a key industrial chemical used in the production of polyethylene terephthalate (PET) polymer, commonly used in plastic bottles, fibers, and films. It consists of a benzene ring with two carboxylic acid groups attached at the para positions. Terephthalic acid is synthesized from petroleum-derived feedstocks and serves as a building block for various polymers and resins. It is valued for its chemical stability, mechanical strength, and versatility in manufacturing synthetic fibers and plastics.
