In organic chemistry, dihydroxybenzenes (benzenediols) are organic compounds in which two hydroxyl groups (−OH) are substituted onto a benzene ring (C6H6). These aromatic compounds are classed as phenols.

Catechol (/ ˈ k æ t ɪ tʃ ɒ l / or / ˈ k æ t ɪ k ɒ l /), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C 6 H 4 (OH) 2. It is the ortho isomer of the three isomeric benzenediols .

2024年5月16日 · Catechol, also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C 6 H 4 (OH) 2. It is a crystalline substance with a distinctive phenolic fragrance. Catechol is an aromatic diol that was originally discovered in 1839 through the dry distillation of catechin by Reinsch.

Catechol is a benzenediol comprising of a benzene core carrying two hydroxy substituents ortho to each other. It has a role as a genotoxin, an allelochemical and a plant metabolite. It is a conjugate acid of a catecholate (1-). View More... benzene-1,2-diol. Computed by Lexichem TK 2.7.0 (PubChem release 2021.10.14)
