  • Applications

    3-Methyloct-1-en-3-ol (CAS 24089-00-7) is a branched alkenyl alcohol used as a fragrance ingredient and odorant in several industries. In practice, it is used as a fragrance component in perfumes and cosmetics, and may act as an intermediate in the synthesis of more complex aroma compounds. It is sometimes evaluated for flavor applications in food processing, and can serve as a scent additive in household cleaning products to impart odor. In some industrial contexts, it may function as a building block for aroma chemical synthesis. Its exact use depends on local regulations and formulation limits.
