Gallic acid, also known as gall acid or gallic acid, is an organic acid, which can be found in gall, hamamelis, lacquer tree, oak bark and tea. Gallic acid is easily soluble in water, alcohol and ether; It has the properties of phenol (easy to be oxidized and ferric chloride aqueous solution to form blue black precipitation) and carboxylic acid (lose carbon dioxide to form pyrogenic gallic acid when heated). Gallic acid can be used as developer, its alkaline bismuth salt is used as preservative, and is commonly used in the pharmaceutical industry. It is the raw material for manufacturing the hallucinogen mescalin.
