  • Applications

    2E,4Z-Heptadien-1-ol (CAS 70979-88-3) is primarily viewed as an intermediate and building block for fragrance and aroma compounds; it is commonly evaluated as a precursor for the synthesis of odorants and can serve as a component in cosmetics/personal care formulations where fragrance is important. Additionally, its conjugated diene-alcohol structure makes it a candidate for flavor-related research and development, and it can function as a reactive intermediate in industrial chemical manufacturing for the synthesis of related organic compounds. Use is subject to local regulations and formulation limits.
