Common Name4-Methylcatechol
Description4-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.
