  • Applications

    Cis-5-Octen-1-ol (CAS 64275-73-6) is a linear unsaturated alcohol with a characteristic fresh green scent, widely employed by the flavour and fragrance industry to impart leafy, cucumber, tropical fruit and mushroom nuances to soft drinks, chewing gum, dairy desserts and ready-to-eat seasonings; in perfumery it serves as a top- and mid-note enhancer that boosts freshness, modulates citrus aldehydes and esters, and lends depth to woody and earthy accords; beyond sensory uses the molecule acts as a versatile intermediate for synthesising insect pheromones, eco-friendly agrochemicals and pharmaceutically relevant derivatives, thanks to the accessible double bond that can be transformed into oximes, esters, epoxides and other functionalised structures.
