Terephthalic acid dipotassium salt（Cat No.:M051449）, with the chemical formula C8H4K2O4, is the potassium salt form of terephthalic acid, a key ingredient in the production of polyesters. This white, crystalline solid is highly soluble in water and is primarily used as an intermediate in the synthesis of high-performance polymers such as polyethylene terephthalate (PET). PET is extensively used in the manufacture of fibers for clothing, containers for liquids and foods, and in thermoforming applications. The dipotassium salt form enhances the compound’s solubility, facilitating various chemical processes in industrial settings.
