1,2,3,5-Tetrahydroxybenzene, also known as pyrogallol, has various uses. It is used in the production of certain dyes, photographic developers, and hair dyes. Additionally, pyrogallol has been employed in traditional medicine and some cosmetic formulations due to its antioxidant properties.
Pyrogallol is an organic compound with the formula C 6 H 3 (OH) 3. It is a water-soluble, white solid although samples are typically brownish because of its sensitivity toward oxygen. [ 3 ] It is one of three isomers of benzenetriols .
Then decarboxylation followed by the cyclization of the activated 3,5-diketoheptanedioate product leads to the formation of phloroglucinol. [16] The enzyme pyrogallol hydroxytransferase uses 1,2,3,5-tetrahydroxybenzene and 1,2,3-trihydroxybenzene (pyrogallol) to produce 1,3,5-trihydroxybenzene (phloroglucinol) and 1,2,3,5-tetrahydroxybenzene.

Thus, the two substrates of this enzyme are 1,2,3,5-tetrahydroxybenzene and 1,2,3-trihydroxybenzene (pyrogallol), whereas its two products are 1,3,5-trihydroxybenzene (phloroglucinol) and 1,2,3,5-tetrahydroxybenzene. This enzyme participates in benzoic acid degradation via CoA ligation.
Other types of resorcinarenes include the related pyrogallolarenes and octahydroxypyridines, derived from pyrogallol and 2,6-dihydroxypyridine, respectively. Resorcinarenes interact with other molecules forming a host–guest complex. [1] Resorcinarenes and pyrogallolarenes self-assemble into larger supramolecular structures.
A pyrogallolarene (also calix[4]pyrogallolarene) is a macrocycle, or a cyclic oligomer, based on the condensation of pyrogallol (1,2,3-trihydroxybenzene) and an aldehyde. Pyrogallolarenes are a type of calixarene , and a subset of resorcinarenes that are substituted with a hydroxyl at the 2-position.
