  • Applications

    Deca-2,4,6-trienal (CAS 25462-05-9) is primarily used as a fragrance ingredient in perfumes and cosmetics, serving as an odorant and helping define the product’s scent profile. It is also regarded as an intermediate in the synthesis of other aroma compounds in industrial manufacturing. Additionally, the compound may appear in household and cleaning products as a fragrance component to improve overall odor. In industrial contexts, it acts as a building block for aroma chemical systems and related compounds, subject to formulation limits and local regulations.
