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. There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. low in high school t shirtWebJun 2, 2024 · Laccase ( para -diphenol:oxygen oxidoreductase, EC 1.10.3.2) is a phenol oxidase widespread in fungi and bacteria.
