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 .
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.
Phloroglucinol is a reagent of the Tollens' test for pentoses. This test relies on reaction of the furfural with phloroglucinol to produce a colored compound with high molar absorptivity. [26] A solution of hydrochloric acid and phloroglucinol is also used for the detection of lignin (Wiesner test).
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 ).
Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. [1] Specialists in this field have a wide array of methods and instruments to help identify unknown substances.
In enzymology, a pyrogallol hydroxytransferase (EC 1.97.1.2) is an enzyme that catalyzes the chemical reaction 1,2,3,5-tetrahydroxybenzene + 1,2,3-trihydroxybenzene ⇌ {\displaystyle \rightleftharpoons } 1,3,5-trihydroxybenzene + 1,2,3,5-tetrahydroxybenzene
