Metabolite Identification
Common Name2,5-Dimethylphenol
Description2,5-Dimethylphenol belongs to the class of organic compounds known as p-xylenols. These are aromatic compounds that contain a p-xylenol moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 4-positions, and at least one hydroxyl group. 2,5-Dimethylphenol is a sweet, bacon, and naphthyl tasting compound. 2,5-Dimethylphenol has been detected, but not quantified in, several different foods, such as alcoholic beverages, arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 2,5-dimethylphenol a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2,5-Dimethylphenol.
