By 1852, Erdmann realized that catechol was benzene with two oxygen atoms added to it; in 1867, August Kekulé realized that catechol was a diol of benzene, so by 1868, catechol was listed as pyrocatechol. [7] In 1879, the Journal of the Chemical Society recommended that catechol be called "catechol", and in the following year, it was listed as ...
Unlike borane itself or alkylboranes, catechol borane exists as a monomer. This behavior is a consequence of the electronic influence of the aryloxy groups that diminish the Lewis acidity of the boron centre. Pinacolborane adopts a similar structure.
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.
Catechol. A catecholamine (/ ˌ k æ t ə ˈ k oʊ l ə m iː n /; abbreviated CA) is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine. [1] Catechol can be either a free molecule or a substituent of a larger molecule, where it represents a 1,2 ...

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]

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 ...
