  • Applications

    Methyl propyl sulphide (CAS 3877-15-4) is a sulfur-containing thioether used across multiple industrial and consumer applications as an odorant and processing aid. In perfumery, it functions as an aroma note (odorant); in flavor formulations, it may contribute to aroma profiles. It is also employed as a fragrance ingredient in cosmetics and personal care products. In industrial manufacturing it can serve as a solvent or processing aid and as an intermediate in organic synthesis, enabling the preparation of other sulfur-containing compounds. In cleaning and household formulations, it may act as a solvent and odorant component to help fragrance and formulation performance.
