Chemical Information
FooDB Name1-(Methylthio)-2-butanone
Description1-(Methylthio)-2-butanone belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. 1-(Methylthio)-2-butanone is a fishy, garlic, and mushroom tasting compound. 1-(Methylthio)-2-butanone has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 1-(methylthio)-2-butanone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 1-(Methylthio)-2-butanone.
