For chemists, formulators, and R&D professionals, a thorough understanding of a chemical compound's properties is the foundation for successful application and innovation. Diethyl Sulfide (CAS: 352-93-2), an organic sulfur compound, presents a unique set of physical and chemical characteristics that define its utility across various sectors, most notably in flavors, fragrances, and certain industrial processes. This article delves into these essential properties, guiding professionals on what to look for when sourcing this compound.

Physically, Diethyl Sulfide is described as a colorless liquid. Its volatility is a key characteristic, with a reported boiling point of approximately 94.4°C at standard atmospheric pressure. This volatility influences its behavior in formulations, particularly in applications where diffusion or evaporation is a factor, such as in aroma release in flavors and fragrances. The melting point is significantly low, around -100°C, indicating it remains liquid under a wide range of typical operating temperatures. Its density is approximately 0.8 to 0.835 g/cm³, making it less dense than water.

Chemically, Diethyl Sulfide (C4H10S) is classified as a thioether, distinguished by the presence of a sulfur atom bonded to two ethyl groups. Its molecular weight is 90.187 g/mol. The compound is known for its distinct, often potent, sulfurous odor, which, in controlled, trace amounts, is highly valued in the flavor and fragrance industries for imparting specific savory, meaty, or roasted notes. Its reactivity profile includes susceptibility to oxidation and the ability to form complexes, which underpins its use as a solvent for certain mineral salts and in electroplating baths.

For professionals seeking to buy Diethyl Sulfide, specifications like purity are paramount. A minimum purity of ≥99.0% is typically required for precise applications in flavors and fragrances, ensuring that the compound's intended olfactory or gustatory impact is not compromised by impurities. The flash point, around -9.4°C to 4°C, categorizes it as a flammable liquid, necessitating careful handling and storage in cool, well-ventilated areas, away from ignition sources. These safety parameters are critical for industrial use and are detailed in the Safety Data Sheet (SDS).
