Gallic acid has many uses in pharmaceuticals, inks, dyes, food, light industry and organic synthesis. Gallic acid and ferric ions form a blue-black precipitate, which is the raw material of blue-black ink; it is also used in leather making industry; it can also be used as a photographic developer. Propyl gallate is an antioxidant and can be used in edible oils to prevent rancidity and deterioration. In medicine, gallic acid is a hemostatic astringent and a mild local irritant.

Gallic acid is a trihydroxybenzoic acid, a type of phenolic acid, a type of organic acid, also known as 3,4,5-trihydroxybenzoic acid, found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants.The chemical formula is C6H2(OH)3COOH. Gallic acid is found both free and as part of hydrolyzable tannins. The gallic acid groups are usually bonded to form dimers such as ellagic acid. Hydrolysable tannins break down on hydrolysis to give gallic acid and glucose or ellagic acid and glucose, known as gallotannins and ellagitannins respectively.
