  • Applications

    trans-2,cis-6-Nonadien-1-ol (CAS 28069-72-9), renowned for its crisp green cucumber and melon character, is widely employed as a flavour and fragrance ingredient to add fresh juicy nuances to soft drinks, non-alcoholic beer, cocktails, chewing gum, confectionery, dairy desserts, salad dressings and savoury snacks; in fine fragrances, skin- and hair-care products, soaps and household cleaners it introduces a sparkling top note that blends well with C-6 aldehydes and herbal accords; it is incorporated into scented candles, wax melts, diffusers and air fresheners to create a garden-like ambience; beyond perfumery it is investigated as an insect attractant or mating-disruption pheromone in sustainable agriculture, serves as an analytical reference standard for GC-MS monitoring of produce freshness, spoilage or pesticide residues, and is supplied neat or in ethanol solutions to flavour houses, research institutes and quality-control laboratories for formulation work and instrument calibration.
