Metabolite Identification
Common Name2,3-Dimethylthiophene
Description2,3-Dimethylthiophene belongs to the class of organic compounds known as heteroaromatic compounds. Heteroaromatic compounds are compounds containing an aromatic ring where a carbon atom is linked to an hetero atom. 2,3-Dimethylthiophene has been detected, but not quantified in, garden onions (Allium cepa). This could make 2,3-dimethylthiophene a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2,3-Dimethylthiophene.
