propyl methanesulfinate

Propyl methanesulfinate is an organosulfur compound characterized by a sulfur atom bonded to a propyl group and a methanesulfinic acid residue. It presents as a chemical substance with distinct sensory notes including green onion and cabbage-like odors, complemented by a touch of surface-ripened cheese at dilute concentrations. Its molecular structure and properties align it within the family of sulfinates, notable for their sulfur-oxygen bonds and utility in organic chemistry. While specific industrial production methods are not detailed, compounds of this type are typically synthesized through oxidation of corresponding sulfides or via specialized chemical routes. The compound's information is accessible through chemical databases such as PubChem, where further structural and physicochemical data can be obtained. Despite its sensory importance, propyl methanesulfinate is not employed in commercial flavor or fragrance formulations, serving primarily academic or research interests.

Propyl methanesulfinate is a sulfur-containing molecule not known to occur naturally in biological systems or foods. Its sensory profile relates to green onion and cabbage aromas often associated with sulfur volatiles in vegetables. In applied contexts, this compound is designated solely for informational purposes and is not used in any fragrances or flavor formulations. It has no recognized status or approval under fragrance industry guidelines such as IFRA (Global) or flavor regulatory frameworks like FEMA (US). Due to the absence of commercial applications, handling and usage recommendations are limited to laboratory or research settings, where it may be examined for structural or olfactory characteristics rather than practical end-use.

Propyl methanesulfinate displays characteristics typical of sulfinates, featuring a polar sulfur-oxygen moiety linked to a small alkyl chain. These molecular features likely confer moderate polarity and potential reactivity under oxidative or reductive conditions. The compound exhibits odor notes identifiable at very low concentrations, indicating high sensory potency. Its solubility profile, while not explicitly detailed, can be inferred to favor polar organic solvents such as propylene glycol where it has been tested for odor evaluation. The relatively low molecular weight facilitates volatility sufficient to contribute to aroma at trace levels. Stability data and comprehensive thermodynamic constants are not documented, reflecting its limited commercial and toxicological study. These properties impact its suitability for formulation, limiting use to analytical or experimental roles rather than product design.
