• Uses: Diethyl sulfide is used as a solvent for anhydrous mineral salts and in plating baths for coating metals with gold or silver. It is used as a flavoring agent. It is also used in the addition reaction with platinum dichloride to prepare platinum ethynyl dimers and polymers with pendant ferrocenyl group. Further, it is used in the preparation of triethylsulfoniuim ethylsulfate by reaction with sulfuric acid diethyl ester. In addition to this, it is used in the quantification procedure of volatile sulfur compounds by solid-phase microextraction. Diethyl sulfide may be used as an analytical standard for the determination of the analyte in wastewater, wines, and beer by gas chromatography (GC) based techniques. Solvent for Anhydrous mineral salts; in plating baths for coating metals with gold or silver.
