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.
