  • Applications

    2-Menthene (CAS 5256-65-5) is primarily used as a chemical intermediate in the synthesis of fragrance and aroma compounds and can serve as an odorant in perfumery and cosmetic formulations. It is often evaluated for potential use as a flavor/aroma component in select formulations. In cosmetics and personal care, it may appear as a fragrance ingredient; in household products, it functions as a scent additive for cleaners and air fresheners. In industrial manufacturing, it serves as an intermediate for the synthesis of terpene-derived materials and related derivatives used in fragrance-related applications and specialty polymers.
