  • Applications

    (2E)-2-Decenol (CAS 18409-18-2) is an unsaturated C10 fatty alcohol widely used in flavor and fragrance applications, contributing fresh green, citrus, softly fruity, slightly fatty–waxy and faint floral nuances that naturalize citrus/green accords and smooth aldehydic edges; accordingly it is dosed at trace-to-low levels in beverage, confectionery, baked goods and chewing-gum flavors, and in fine fragrances, soaps, detergents, personal care and deodorizing products to tune top–heart notes, boost diffusion and substantivity; in aroma-chemical synthesis, (E)-2-decenol serves as an intermediate for 2-decenyl esters (e.g., acetate, propionate) with fruity–citrus character and as a building block for specialty derivatives (e.g., ethoxylated forms used as nonionic surfactants); in R&D it functions as an analytical standard/reference in studies of food/beverage volatiles, lipid oxidation pathways, metabolic fate and odor stability in formulations; specific uses and dosages should follow local regulations and industry safety guidance (e.g., IFRA/FEMA, flavor standards).
