| Common Name | 4-(Methylthio)-2-butanone |
|---|
| Description | 4-(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. 4-(Methylthio)-2-butanone is a sweet, earthy, and fruit tasting compound. Based on a literature review very few articles have been published on 4-(Methylthio)-2-butanone. |
