Applications

Organic acid is used as a standard for determining phenols in the Folin-Ciocalteau assay3,4,5-Trihydroxybenzoic acid is used as a cyclooxygease inhibitor substance, which is found in plants. In analytical chemistry, it is used as a standard to determine phenol content in various analytes. It acts as a starting material for the preparation of psychedelic alkaloid mescaline. Further, it is used to produce polyesters based on phloretic acid and gallic acid. In addition to this, it is used in the preparation of its esters such as methyl gallate, ethyl gallate, propyl gallate, octyl gallate and doceyl gallate.

Notes

Hygroscopic. Light sensitive. Incompatible with strong oxidizing agents, strong bases, acid anhydrides, acid chlorides, metals.
