Metabolite Identification
Common Name3-Methylcatechol
Description3-methylcatechol, also known as 2,3-dihydroxytoluene or 2,3-toluenediol, is a member of the class of compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3-methylcatechol is soluble (in water) and a very weakly acidic compound (based on its pKa). 3-methylcatechol can be found in arabica coffee, beer, cocoa powder, and coffee, which makes 3-methylcatechol a potential biomarker for the consumption of these food products. 3-methylcatechol is a chemical compound .
