Allyl methyl sulfide is a sulfur-containing , unsaturated organic compound from the group of thioethers . In addition to the sulfide group, a C = C double bond occurs in the molecule .
Occurrence
Allyl methyl sulfide occurs - in addition to the odorless compounds allyl methyl sulfoxide (AMSO) and allyl methyl sulfone (AMSO2) - as a garlic-like smelling metabolic breakdown product of allicin , the aromatic substance of garlic . The organic sulfur compound is responsible for the smell of the breath like garlic consumption and can also be detected in human breast milk, for example.
Extraction and presentation
The laboratory synthesis succeeds by reacting allyl chloride and methanethiol in the presence of sodium hydroxide .
properties
In its pure state, allyl methyl sulfide forms an easily flammable, colorless liquid with an intense odor that is characteristic of alkyl sulfides .
