  • Applications

    Trans,trans-2,4-Nonadienal (CAS 5910-87-2) is an unsaturated aldehyde with a characteristic “fried-fat, cucumber, almond” aroma that is widely used as a flavoring agent in potato chips, margarine, salad dressings, beer and soft drinks, as a sensory reference for assessing the freshness of seafood and vegetables, as a “green-fatty” note in fine fragrances, as a chemical indicator of lipid oxidation in food-packaging studies, as a GC-MS calibration compound for shelf-life analysis, and as a semiochemical cue in mosquito and drosophila pheromone research.
