  • Applications

    Methyl 2-methyl-3-furyl disulfide (CAS 65505-17-1) is primarily used as a specialty odorant in fragrance formulations, where it contributes sulfurous or furanyl notes; it may also be evaluated as a flavor/aroma ingredient in selected products. In cosmetics and personal care, it can serve as a fragrance component; in household products such as air fresheners and cleaners, it is used to impart characteristic scents. In coatings and inks and other industrial formulations, it can be employed as a fragrance additive or odorant. It can also be used as an intermediate in the synthesis of other sulfur-containing furans or related aroma compounds. Its use is typically controlled by formulation limits and local regulations.
