Gallic acid anhydrous powder (CAS 149-91-7) is obtained from nutgalls and other plants or by the hydrolysis of tannic acid with sulfuric acid. Gallic acid exists in white crystalline powder,soluble in water (11.5 mg/ml), ethanol, acetone, and Alcohol. Insoluble in chloroform. Gallic acid is commonly used in the pharmaceutical industry. It is used as a standard for determining the phenol content of various analytes by the Folin-Ciocalteau assay; results are reported in gallic acid equivalents. Gallic acid can also be used as a starting material in the synthesis of the psychedelic alkaloid mescaline.
