  • Applications

    2-Methyl-1-penten-3-ol (CAS 2088-07-5) is principally used as an intermediate in fragrance and flavor chemistry, serving as a precursor for the synthesis of a range of aroma compounds via esterification or oxidation. It is commonly evaluated for use as a fragrance ingredient in cosmetics and personal care, and may appear in perfumed household products such as cleaners and detergents. In industrial manufacturing, it acts as a synthetic building block for fragrance-related intermediates and derivative compounds. It can also be encountered in polymer-related formulations as a fragrance component or in fragrance-release systems within polymer materials, depending on formulation requirements and regulatory constraints.
