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 .
A hydrolysable tannin or pyrogallol-type tannin is a type of tannin that, on heating with hydrochloric or sulfuric acids, yields gallic or ellagic acids. [ 1 ] At the center of a hydrolysable tannin molecule , there is a carbohydrate (usually D-glucose but also cyclitols like quinic or shikimic acids ).
In some countries and in veterinary medicine, phloroglucinol is used as a treatment for gallstones, spasmodic pain and other related gastrointestinal disorders [17] A 2018 review found insufficient evidence that phloroglucinol was effective for treating abdominal pain [18] A 2020 review found insufficient evidence that phloroglucinol was ...
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.
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.

Despite the importance Medicaid places on providing access to health care, many states have inconsistent policies toward paying for medications used to treat opiate addiction. The American Society of Addiction Medicine surveyed each state’s Medicaid program to determine which medications are covered and if any limitations exist.
It is the symmetrically dimethylated derivative of pyrogallol. It is a colorless solid, although typical samples are brown owing to air-oxidized impurities. Together with guaiacol, syringol and its derivatives are produced by the pyrolysis of lignin. Specifically, syringol is derived from the thermal decomposition of the sinapyl alcohol component.
