Documented uses

• The main volatile oil in onions, it is used as a food flavoring agent. [ACGIH]
• Synthetic flavor; food additive
• Flavouring Agent -> FLAVOURING_AGENT -> JECFA Functional Classes
• Flavoring Agents -> JECFA Flavorings Index
• Treatment of 1-ethylthio-2-propenylthioethene with NaNH2 in liquid ammonia results in formation of Na-1-propenethiolate, which reacts with s-propyl propanethiosulfonate to give propenyl propyl disulfide in good yield.
• The chief volatile constituent of onion oil.
