furfuryl propyl sulfide

Furfuryl propyl sulfide, also referred to by its trivial name 2-[(propylsulfanyl)methyl]furan, is a sulfur-containing heterocyclic organic compound with the molecular formula C₉H₁₄S. It appears as a compound with specific sensory characteristics notably an onion-like aroma profile. This compound belongs to the class of organosulfur chemicals characterized by a furan ring bound to a propylsulfanyl side group, which contributes to its distinctive organoleptic properties. The substance is cataloged under various chemical identifiers and documented in [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/528330) reflecting its recognized chemical structure and properties. Furfuryl propyl sulfide is derived synthetically and is not typically isolated from natural sources in significant amounts. Its usage is restricted to informational and research contexts rather than commercial flavor or fragrance applications.

Furfuryl propyl sulfide is not naturally prevalent in biological systems but is a synthetic organosulfur compound mainly of interest for chemical characterization. Due to its potent onion flavor note, there might be interest in its sensory relevance as a reference or comparative compound. It does not see use in the formulation of fragrances or food flavors, as confirmed by regulatory recommendations. The substance is primarily retained within informational repositories or research environments for study rather than commercial application. Its handling and potential use fall outside the scope of the flavor and fragrance industries under standards such as FEMA (US), reflecting its non-inclusion in regulated product categories.

Furfuryl propyl sulfide exhibits a moderate estimated partition coefficient (log P) of approximately 2.8, indicating moderate lipophilicity which influences its solubility and interaction with solvents. It has a vapor pressure of 0.335 mmHg measured at 25 °C, demonstrating moderate volatility relevant to handling and potential evaporation. The flash point is reported as 174 °F (approximately 79 °C), which provides information about its flammability threshold. The compound is soluble in alcohol solvents and has an estimated low solubility in water near 203.4 mg/L at 25 °C, signifying limited aqueous dispersibility. These properties collectively inform considerations in formulation, storage, and experimental use contexts.
