Description	Gallic acid (also known as 3,4,5-trihydroxybenzoic acid) is a trihydroxybenzoic acid with the formula C6H2(OH)3CO2H. It is classified as a phenolic acid. It is found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. It is a white solid, although samples are typically brown owing to partial oxidation. Salts and esters of gallic acid are termed "gallates".

 

 

It is used in the pharmaceutical industry as a standard for determining the p henol content (a large group of several hundred chemical substances) of various analytes by the Folin-Ciocalteau assay. In addition, it is used as a starting material in the synthesis of the naturally occurring alkaloid m escaline, and as an ink dye by early photographers to develop images. When heated to 200°-250° C, gallic acid splits into pyrogallol (pyrogallic acid) and carbon dioxide.
