Description	Dibutyl sulfide (also named as butyl sulfide; N-butyl sulfide; Di-n-butyl sulfide; butylthiobutane), a colorless to pale yellow clear liquid, is a symmetric thioether. Dibutyl sulfide is found in raw cabbage, boiled and cooked beef, and some varieties of mushroom. Dibutyl sulfide is typically used as a flavoring agent. As a thioether, dibutyl sulfide has applications in organic synthesis as a solvent as well as a reagent. It is used to synthesize specific compound classes including property-enhancing additives, pharmacological drugs, chemical resistant polymers, detergents, and rubber antioxidants. Dibutyl sulfide can also be used as an agricultural intermediate, a sulfiding agent, a refinery catalyst, a lubricant additive, a gas odorant, and a processing aid in mining applications. Furthermore, it can be used as an internal standard in X-ray fluorescence spectrometry (XRF) measurements of sulfur in oils and other liquid hydrocarbon matrices.

Chemical Properties	colourless liquid with a very unpleasant smell
Chemical Properties	Butyl sulfide has an herbaceous, green, garlic, onion, heavy odor.
Occurrence	Reported found in raw cabbage, cooked beef and mushrooms.
Preparation	From butyl bromide and sodium sulfide in boiling ethanol; according to some authors two forms exist, exhibiting different boiling points but identical solubilities in various solvents; both forms are insoluble in water.
Aroma threshold values	Recognition: 0.88 ppb
Purification Methods	Wash the sulfide with aqueous 5% NaOH, then water. Dry with CaCl2 and distil it from sodium. [Beilstein 1 IV 1559.]
