Methylthioethane Usage And Synthesis

Chemical Properties	clear colorless liquid
Chemical Properties	Methyl ethyl sulfide has a cabbage-like odor.
Occurrence	Reported found in tomato, cooked chicken, beef and pork, rum, bourbon, whiskey, cocoa and coffee
Uses	Ethyl Methyl Sulfide is used as a corrosion inhibitor for zinc metal which finds wide applications like electrode material in batteries, sacrificial anodes and metallic coatings. It is used in mixtures designed to odorize natural gas and is made to by-pass injection system.
Aroma threshold values	Aroma characteristics at 0.1%: sulfurous, tomato and cabbage vegetative with dimethyl sulfide, meaty and metallic nuances.
Taste threshold values	Taste characteristics at 0.25 to 2 ppm: sulfurous, vegetative, dimethyl sulfide-like sweet corn notes, eggy, meaty and clam nuances
General Description	Microwave spectra of the trans isomer of ethyl methyl sulfide and its 10 isotopic species has been investigated. Chlorination of ethyl methyl sulfide with N-chlorosuccinimide and sulfuryl chloride has been reported.
