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.
4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol. [1] TBC is available in the form of a solid crystal flake [2] and 85% solution in methanol [3] or water. [4]
Calone, a derivative of 4-methylcatechol, is known in the fragrance industry as "watermelon ketone" for its distinctive odor. [3]The brand of low-temperature coke used as a smokeless fuel Coalite obtains homocatechol from ammoniacal liquor by solvent extraction, distillation and crystallisation.
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. [1]
The Dakin oxidation is most commonly used to synthesize benzenediols [8] and alkoxyphenols. [ 1 ] [ 9 ] Catechol , for example, is synthesized from o -hydroxy and o -alkoxy phenyl aldehydes and ketones, [ 8 ] and is used as the starting material for synthesis of several compounds, including the catecholamines , [ 10 ] catecholamine derivatives ...

Catecholborane may be used as a stereoselective reducing agent when converting β-hydroxy ketones to syn 1,3-diols. Catecholborane oxidatively adds to low valent metal complexes, affording boryl complexes. [5] C 6 H 4 O 2 BH + Pt(PR 3) 2 → (C 6 H 4 O 2 B)Pt(PR 3) 2 H
Figure 1. The overall reaction of catechol 1,2-dioxygenase. Using a non-heme iron(III) complex, 1,2-CTD is able to oxidatively cleave catechol into cis,cis-muconic acid. More specifically, 1,2-CTD is an intradiol dioxygenase, a family of catechol dioxygenases that cleaves the bond between the phenolic hydroxyl groups of catechol using an Fe 3 ...
