Terephthalic acid is an aromatic dicarboxylic acid primarily used as a precursor in the production of polyethylene terephthalate (PET) plastics and fibers. It plays a crucial role in the manufacture of textiles, packaging materials, and bottles. The compound is produced industrially by the oxidation of p-xylene.
