3-Mercapto-2-butanone Usage And Synthesis

Chemical Properties	Colorless liquid
Uses	3-Sulfanylbutan-2-one can be used to treating inflammation-??related diseases.
Definition	ChEBI: 3-Mercapto-2-butanone is a ketone.
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.
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
