Gallic acid is a trihydroxybenzoic acid found widely in plants, notably in gallnuts, sumac, witch hazel, tea leaves, and oak bark. It is commercially produced by the hydrolysis of tannins, primarily tannic acid, followed by purification to a high-purity crystalline form. This product is offered at ≥99.0% purity (HPLC), suitable for pharmaceutical, nutraceutical, and industrial applications.
As a versatile phenolic acid, gallic acid serves as a key intermediate in the synthesis of propyl gallate, trimethoprim, and other pharmaceuticals. Its antioxidant and astringent properties make it valuable in skin care, food preservation, and as a reference standard in analytical laboratories. The global demand for gallic acid is driven by its expanding use in the pharmaceutical and food industries, particularly in Asia and Europe.
