Metabolite Identification
Common Name2-Ethyl-p-xylene
Description2-Ethyl-p-xylene belongs to the class of organic compounds known as p-xylenes. These are aromatic compounds that contain a p-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 4-positions. 2-Ethyl-p-xylene is possibly neutral. These are compounds containing a benzene ring which bears a methane group.
