| Description | o-Xylene, also known as O-dimethylbenzene or O-methyltoluene, belongs to the class of organic compounds known as o-xylenes. These are aromatic compounds that contain a o-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 2-positions. o-Xylene is possibly neutral. o-Xylene is a geranium tasting compound. Outside of the human body, o-Xylene is found, on average, in the highest concentration within black walnuts. o-Xylene has also been detected, but not quantified in, several different foods, such as sweet cherries, cucumbers, evergreen blackberries, corns, and cauliflowers. This could make O-xylene a potential biomarker for the consumption of these foods. o-Xylene is a potentially toxic compound. |
