  • Applications

    Compound 2,6-Dimethyloct-7-en-2-yl formate (CAS 25279-09-8) is primarily used as a fragrance ingredient in perfumery, where its terpene-like skeleton contributes to distinctive aroma notes and may serve as a fixative to extend scent longevity. In cosmetics and personal care, it is considered a fragrance component for adding and stabilizing aroma in products such as lotions, bath products, and hair care. In household and cleaning products, it can be used as an odorant additive to impart a pleasant scent in cleaners, detergents, and air fresheners. In industrial manufacturing, it may serve as an intermediate in fragrance synthesis or related organic synthesis work, enabling the formation of aroma esters and other building blocks; its use is subject to local regulations and formulation limits.
