Chemical Information
FooDB Name4-Methyl-1,2-benzenediol
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. 4-Methylcatechol is found, on average, in the highest concentration within a few different foods, such as arabica coffees (Coffea arabica), robusta coffees (Coffea canephora), and coffees (Coffea) and in a lower concentration in cocoa powder and beer. 4-Methylcatechol has also been detected, but not quantified in, several different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), domestic pigs (Sus scrofa domestica), and eggplants (Solanum melongena). This could make 4-methylcatechol a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 4-Methylcatechol.
