  • Applications

    (2E,4E)-2,4-Decadien-1-ol (CAS 18409-21-7) is a flavor and fragrance ingredient used to impart and modulate fresh green, slightly fatty, and crisp fruity nuances (melon-like, citrus peel, green-pear facets) in food and beverage flavors—rounding bases, masking off-notes from fats, and adding lift to top notes; in perfumery and personal/home care it provides leafy-herbal, oily-green brightness that supports citrus, tea, marine, and aldehydic accords and enhances the naturality of fruit notes; the (2E,4E) geometry offers a cleaner, more consistent odor profile, and the material is also employed as a reference standard for GC-olfactometry/GC-MS in aroma research and as a synthetic intermediate toward other aroma chemicals and certain pheromone motifs; it is typically dosed at trace-to-low ppm under applicable flavor/fragrance regulations (e.g., IFRA, regional food-flavor standards) and stored tightly closed away from light/oxygen to minimize oxidation to related aldehydes.
