Metabolite Identification
Common Namem-Xylene
Descriptionm-Xylene, also known as 1,3-xylene or m-dimethylbenzene, belongs to the class of organic compounds known as m-xylenes. These are aromatic compounds that contain a m-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 3-positions. The conversion m-xylene to isophthalic acid entails catalytic oxidation. m-Xylene (meta-xylene) is an aromatic hydrocarbon. m-Xylene is possibly neutral. m-Xylene is a plastic tasting compound. m-xylene is found, on average, in the highest concentration in safflowers. m-xylene has also been detected, but not quantified, in black walnuts and parsley. This could make m-xylene a potential biomarker for the consumption of these foods. Xylenes are not acutely toxic, for example the LD50 (rat, oral) is 4300 mg/kg. m-Xylene is a potentially toxic compound. Concerns with xylenes focus on narcotic effects. The m- stands for meta-, indicating that the two methyl groups in m-xylene occupy positions 1 and 3 on a benzene ring. All xylene isomers are colorless and highly flammable. Petroleum contains about 1 weight percent xylenes.
