  • Applications

    cis-4-Decenal (CAS 21662-09-9) is a straight-chain aldehyde with a characteristic fruity, green and slightly fatty note that finds broad application in flavour and fragrance work, where it recreates orange, grapefruit, peach, passionfruit and refined “green” nuances in candies, beverages, dairy, plant-based foods and savoury products, while also providing aldehydic depth to fine perfumes, scented candles, premium detergents and personal-care formulations; in the analytical arena it serves as a GC-MS reference standard for quantifying trace aroma compounds, studying edible-oil oxidation, monitoring insect pheromone blends and tracking the development of off-flavours in food, thereby supporting formulation design, quality control and advanced sensory research.
