Allyl mercaptan Usage And Synthesis

Chemical Properties

colourless to faintly yellow-brown liquid

Chemical Properties

A colorless liquid with strong garlic odor. Used as a flavor enhancer, flavoring agent or adjuvant

Occurrence

Reported found in onion, garlic and caucas (Allium victoralis L.).

Uses

Allyl mercaptan is an important raw material and intermediate used in organic synthesis, pharmaceuticals agrochemicals and dyestuff fields.

Uses

Allyl Mercaptan is a synthetic flavoring agent that is a stable, color- less liquid of garlic-like odor. it should be stored in glass or tin con- tainers. it is used in artificial garlic flavors for application in condiments at 3 ppm, and in baked goods at 2 ppm. it is also termed 2 propylene-1 thiol.

Definition

ChEBI: 2-Propene-1-thiol is an alkanethiol.

Preparation

Produced from Ally] bromide and Potassium hydrosulfide.

Aroma threshold values

Detection: 0.005 ppb

Safety Profile

Poison by inhalation and ingestion. Strong irritant to skin and mucous membranes. When heated to decomposition it emits highly toxic fumes of SO,. Very dangerous fire hazard. To fight fire, use water mist or spray, alcohol foam, Con, or dry chemical. See also ALLYL COMPOUNDS and MERCAPTANS
