  • Product Details

Gallic acid is kind of plant extract from nutgalls and other plants. This is the common nutural one we have. But in market there is another kind of gallic acid which can be got by hydrolysis of tannic acid with sulfuric acid.  


TNJ Chemical has Gallic acid monohydrate and Gallic acid anhydrous (two kinds). Normally speaking, Gallic acid anhydrous is used for cosmetic and pharmaceuticals etc with high demand for quality; While monohydrate is often used for industrial use with no high demand for water content.


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.
