Common Name4-Methylthio-2-butanone
Description4-(Methylthio)-2-butanone, also known as FEMA 3375, 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 will be an enol. 4-(Methylthio)-2-butanone is an essentially neutral compound. It is a colorless to pale yellow clear liquid that is insoluble in water and soluble in alcohol. 4-(Methylthio)-2-butanone has a sulfurous, vegetative, potato, earthy, tomato, metallic and fatty odor and a sulfurous, potato, earthy, vegetable, fatty, fishy, metallic, mushroom taste ( Ref:DOI ). It is found in kohlrabi stem and roasted sesame seed. 4-(Methylthio)-2-butanone is a constituent of marijuana smoke ( Ref:DOI ). 4-(Methylthio)-2-butanone is formed during the combustion of cannabis.
