4-methyl-2-[2-(methyl thio)ethyl]-1,3-oxathiane

4-methyl-2-[2-(methyl thio)ethyl]-1,3-oxathiane is an organosulfur compound structurally characterized by a 1,3-oxathiane ring substituted with methyl and methylthioethyl groups. This compound exhibits a distinctly potent garlic-like odor accompanied by animalic, onion, green, herbaceous, raw vegetable, and potato nuances at low concentrations, such as 0.10% in propylene glycol. Its notable organoleptic properties arise from the sulfur moiety contributing to its characteristic aroma profile. Also referred to as 4-methyl-2-[2-(methylthio)ethyl]-1,3-oxathiane, it is primarily documented in chemical literature and flavor chemistry databases such as PubChem. This compound is not widely employed in commercial fragrance or flavor formulations but is studied for its sensory and chemical characteristics, often as a reference in sulfur-containing odorant research.

This compound does not naturally occur in significant biological contexts but is of interest in the study of sulfur-based odorants. Due to its intense garlic and green herbaceous odor notes, 4-methyl-2-[2-(methyl thio)ethyl]-1,3-oxathiane holds potential as a model compound for understanding sulfurous aroma impact in various matrices. Although it is not used commercially in fragrances or flavors, it may have applications in scientific research related to organosulfur chemistry. Standards such as FEMA (US) classify it as an informational compound without established usage levels for fragrance or flavor applications, relating to its limited practical application in consumer products.

The physico-chemical characteristics of 4-methyl-2-[2-(methyl thio)ethyl]-1,3-oxathiane reflect its sulfur-containing heterocyclic structure, imparting significant volatility and a pronounced odor profile. Its molecular features contribute to its solubility behaviors and interaction with solvents like propylene glycol, which is commonly used for sensory evaluation. The presence of sulfur and the oxathiane ring influences its thermal stability and reactivity, factors relevant for handling and analysis but limiting for formulation in consumer products. Its odor potency at low concentrations necessitates careful control when studied analytically. Although detailed thermodynamic and spectral data are limited, these properties determine its sensory impact and guide scientific investigation rather than commercial application.
