Bis(methylthio)methane丨CAS 1618-26-4

Bis(methylthio)methane is a sulfur-containing organic compound widely used in flavor and fragrance chemistry, organic synthesis, and chemical research. In the flavor industry, it is employed as a key aroma compound to impart meaty, roasted, and savory notes in seasonings, processed foods, and meat analogues. Its distinct sulfurous odor makes it valuable in recreating natural cooked meat flavors and enhancing flavor profiles in food formulations. In organic synthesis, bis(methylthio)methane serves as a methylthio transfer reagent, a building block for the synthesis of heterocyclic compounds such as thiazoles and thiadiazoles, and a precursor for pharmaceuticals and agrochemicals. It is also used in chemical research to study sulfur-based reactions, nucleophilic substitutions, and the formation of sulfur-containing intermediates.

The compound offers several advantages due to its high reactivity and potent aroma profile. Its sulfur-containing functional groups allow selective methylthio transfer, facilitating efficient synthesis of heterocyclic and bioactive molecules. Even at low concentrations, bis(methylthio)methane imparts strong savory and roasted odor characteristics, enhancing flavor perception and product quality. The compound is relatively stable under proper storage conditions, soluble in organic solvents, and compatible with various reaction conditions, which makes it convenient for both laboratory and industrial applications. Additionally, its dual role as a flavoring agent and reactive intermediate provides versatility across food chemistry and synthetic chemistry sectors.
