Metabolite Identification
Common Name2,6-Dimethyl-1,4-benzenediol
Description2,6-Dimethyl-1,4-benzenediol, also known as 2, 6-dimethyl-p-benzohydroquinone or 2, 6-xylohydroquinone, belongs to the class of organic compounds known as hydroquinones. Hydroquinones are compounds containing a hydroquinone moiety, which consists of a benzene ring with a hydroxyl groups at positions 1 and 4. 2,6-Dimethyl-1,4-benzenediol has been detected, but not quantified, in a few different foods, such as broccoli, common pea, and pulses. This could make 2,6-dimethyl-1,4-benzenediol a potential biomarker for the consumption of these foods.
