  • Applications

    2-Methyl-3-furanthiol (CAS 28588-74-1) is a sulfur-containing mercaptan with a strong odor and is considered as an aroma and flavor ingredient in industrial applications. In the fragrance and perfume sector, it is used at very low concentrations to impart roasted-meat or onion-like notes, helping shape complex odor profiles. In flavor applications and food processing, it is evaluated as a specialty aroma component to reproduce meat and savory notes. In cosmetics/personal care and household products, it may serve as a fragrance ingredient; in industrial manufacturing, it is used as an organic intermediate for synthesizing other sulfur-containing aroma compounds. Use and dosages depend on local regulations and formulation specifics.
