Pyrocatechol, often known as catechol or benzene-1,2-diol, is a benzenediol, with formula C6H4(OH)2. It was first prepared in 1839 by H. Reinsch by distilling catechin (the juice of Mimosa catechu). This colourless compound occurs naturally, but about 20000 tons are manufactured each year, mainly as precursors to pesticides, flavors, and fragrances. Its sulfonic acid is often present in the urine of many mammals. Small amounts of catechol occur naturally in fruits and vegetables, along with the enzyme polyphenol oxidase. Upon mixing the enzyme with the substrate and exposure to oxygen (as when a potato or apple is cut), the colorless catechol oxidizes to reddish-brown benzoquinone derivatives. The enzyme is inactivated by adding an acid, such as lemon juice, or by refrigeration. Excluding oxygen also prevents the browning reaction. Catechol melts at 28 °C and boils at 250 °C. It is employed in medicine as an expectorant. The dimethyl ether or veratrol is also used in medicine. Many other pyrocatechin derivatives have been suggested for therapeutic application. Pyrocatechol has also been found to be a microbial metabolite in Escherichia, Mycobacterium and Pseudomonas (PMID:19300498; PMID:25281236). Constituent of variety foodstuffs especies coffee, cocoa, bread crust, roasted malt and beer; Isolated from various plant sources and by hydrolysis of tannins (CCD). 1,2-Benzenediol is found in many foods, some of which are chervil, black raspberry, swede, and wasabi.

4-Methylcatechol

4-Methyl-1,2-dihydroxybenzene

C7H8O2 (124.05242679999999)


4-Methylcatechol, also known as homocatechol or toluene-3,4-diol, belongs to the class of organic compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. Outside of the human body, 4-Methylcatechol is found, on average, in the highest concentration within a few different foods such as coffee and cocoa powders and in a lower concentration in beers. 4-Methylcatechol has also been detected, but not quantified in eggplants. This could make 4-methylcatechol a potential biomarker for the consumption of these foods. Recent studies have suggested that a lack of brain-derived neurotrophic factor (BDNF) in the limbic system may cause neuropathic pain (PMID:22198556). It is both a substrate and a suicide inhibitor of catechol 2,3-dioxygenase (PMID:15006807). 4-Methylcatechol is a metabolite of homoprotocatechuic acid (PMID:4974346). 4-Methylcatechol is known to induce the production of BDNF. 4-methylcatechol is a metabolite of homoprotocatechuic acid. It is both a substrate and a suicide inhibitor of Catechol 2,3-dioxygenase [EC 1.3.11.2]. (PMID 15006807) [HMDB]. 4-Methyl-1,2-benzenediol is found in many foods, some of which are coffee, beer, arabica coffee, and cocoa powder. 4-Methylcatechol, a metabolite of p-toluate, is a substrate as well as a suicide inhibitor of Catechol 2,3-Dioxygenase. 4-Methylcatechol, a metabolite of p-toluate, is a substrate as well as a suicide inhibitor of Catechol 2,3-Dioxygenase.
