| | 3-Mercapto-2-butanone Usage And Synthesis |
| Chemical Properties | Colorless liquid | | Uses | 3-Sulfanylbutan-2-one can be used to treating inflammation-related diseases. | | Preparation | From 2,4,5-trimethyl-2-ethyl-3-thiazoline with butyl and hydrolysis; from oxo-compound with sulfur or polysulfides and
ammonia at room temperature. | | Definition | ChEBI: 3-Mercapto-2-butanone is a ketone. | | General Description | 3-Mercapto-2-butanone is a sulfur-containing flavor compound mainly found in meat and meat products. It is formed by the Maillard reaction between sugars and cysteine or thiamin, which are known precursors for meat-like flavorings. | | Biochem/physiol Actions | Taste at 0.3-1.0 ppm |
