  • Applications

    2-Methyl-6-methyleneoct-7-en-2-yl formate (CAS number: 71617-16-8) is a terpenoid-like formate ester used as a fragrance ingredient. In perfumery, it contributes distinctive aroma notes and can function as a fixative to help fragrances linger. In cosmetics and personal care, it is employed as a fragrance component in products such as lotions and creams. In household products, it is utilized as a scent additive in cleaners, air fresheners, and laundry products to impart a lasting fragrance. It may also serve as an intermediate in fragrance synthesis and could have applicability in coatings and inks where odorants are desired. Use is subject to local regulations and formulation limits.
