3-(Methylthio)propionaldehyde is the major product of chemical methionine conversion via Strecker degradation in food. It is a reactant involved in homolytic cross-coupling reactions, oxidative coupling and chemoselective oxidation, intermolecular alkyne hydroacylation reactions and oxxidation of sulfides to sulfoxides.3-(Methylthio)propionaldehyde is used as biosynthetic precursor of ethylene1.Reactant involved in: · Homolytic cross-coupling reactions · Oxidative coupling and chemoselective oxidation · Intermolecular alkyne hydroacylation reactions · Oxidation of sulfides to sulfoxides 3-(Methylthio)propionaldehyde is the major product of chemical methionine conversion via Strecker degradation in food.
