Metabolite Identification
Common NameEthylbenzene
DescriptionEthylbenzene, also known as ethylbenzol or phenylethane, belongs to the class of organic compounds known as benzene and substituted derivatives. These are aromatic compounds containing one monocyclic ring system consisting of benzene. Ethylbenzene exists as a solid and is considered to be practically insoluble (in water) and relatively neutral. Ethylbenzene has been detected in multiple biofluids, such as feces and blood. Within the cell, ethylbenzene is primarily located in the membrane (predicted from logP). Ethylbenzene exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, ethylbenzene can be found in black walnut and safflower. This makes ethylbenzene a potential biomarker for the consumption of these food products. Ethylbenzene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound.
