Description Terephthalic acid (a portmanteau of the turpentine producing tree terebinthus, and phthalic acid) is the organic compound with formula C6H4(CO2H)2. This White solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tonnes are produced annually.

Application Terephthalic acid (TPA) can be synthesized from bio-based materials for a variety of s, which include the production of polyester fiber, non-fiber field, PET bottles, synthetic perfumes and medicines.
Terephthalic acid is used as a linker molecule in the preparation of metal organic frameworks (MOFs).
