CH2CH32S

CH2CH32S, more commonly known as diethyl sulfide, is an organosulfur compound with the chemical formula (CH3CH2)2S. It is a colorless liquid with a characteristic, strong, and often unpleasant odor. Diethyl sulfide belongs to the class of thioethers, which are organic compounds containing a sulfur atom bonded to two alkyl or aryl groups.

Diethyl sulfide is soluble in most organic solvents but has limited solubility in water. Its boiling point is approximately 92 degrees Celsius. It is a relatively stable compound under normal conditions but can be oxidized to form sulfoxides and sulfones.

This compound finds various applications, though its use is often limited by its strong odor. It can be employed as a solvent, particularly in organic synthesis. Diethyl sulfide has also been investigated for its potential as a flavoring agent in certain food products, albeit in very small, controlled quantities. Historically, it has been used in the past as a component in some perfumes, contributing to specific olfactory profiles. It is also sometimes used in research settings as a reagent or a reference compound. Due to its distinct smell, it has also been considered for use as an odorant for natural gas to help detect leaks, although other sulfur compounds are more commonly used for this purpose.
