Metabolite Identification

Common Name

3-Ethyl-5-methylphenol

Description

3-Ethyl-5-methylphenol belongs to the class of organic compounds known as meta cresols. These are aromatic compounds containing a meta-cresol moiety, which consists of a benzene ring bearing a methyl group and a hydroxyl group at ring positions 1 and 3, respectively. 3-Ethyl-5-methylphenol has been detected, but not quantified in, breakfast cereal and cereals and cereal products. This could make 3-ethyl-5-methylphenol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3-Ethyl-5-methylphenol.
