  • Applications

    1-Hexen-3-ol (CAS 4798-44-1) is a secondary, allylic unsaturated alcohol used broadly in fragrance to impart fresh green, leafy, cucumber-like and light fruity facets in fine fragrances, personal care, and household perfumery, enhancing naturality, diffusion, and bridging citrus, herbal, and floral accords; in flavors it is dosed at trace levels to reinforce crisp green notes of apple, pear, melon, and vegetables across beverages, confectionery, cultured dairy, and cereal-based products; in R&D and analytics it serves as a GC–MS/GC–O reference and spiking standard for sensory-impact studies and matrix interactions; additionally, its allylic alcohol motif makes it a versatile building block in the synthesis of aroma esters (e.g., acetate derivatives), as well as pharmaceutical, agrochemical, and other organic intermediates via common transformations such as esterification, selective oxidation, or double-bond modification; usage should align with appropriate food/cosmetic grade selection and applicable safety and regulatory guidance (e.g., IFRA, FEMA/GRAS, SDS).
