Metabolite Identification
Common Name5-Methyl-2-furanmethanethiol
Description5-Methyl-2-furanmethanethiol 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. 5-Methyl-2-furanmethanethiol is a coffee, roasted, and sulfurous tasting compound. 5-Methyl-2-furanmethanethiol has been detected, but not quantified in, several different foods, such as oyster mushrooms (Pleurotus ostreatus), cereals and cereal products, breakfast cereal, coffee and coffee products, and common mushrooms (Agaricus bisporus). This could make 5-methyl-2-furanmethanethiol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5-Methyl-2-furanmethanethiol.
