  • Applications

    Oct-7-en-1-ol (CAS 13175-44-5) is a linear ω-unsaturated primary alcohol that combines a terminal C=C bond with a reactive –OH group; this dual functionality enables its use as an intermediate in flavors and fragrances (esterification to 7‑octenyl acetate and other long-chain esters, hydrogenation/epoxidation to tailor odor profiles), as a monomer/functional modifier in polymer and materials chemistry (acrylation or maleation to make UV-curable oligomers, thiol–ene or hydrosilylation to graft onto silicones, polyolefins and surfaces, epoxidation of the double bond to obtain epoxy-functional reactive diluents for epoxy resins), as a feedstock for surfactants and wetting agents via ethoxylation/propoxylation, as an intermediate for agricultural pheromones and insect lures (through selective ω-double-bond esterification/acetylation/hydroformylation), and as a precursor to the corresponding diols, aldehydes or acids via hydroformylation, dihydroxylation and controlled oxidation; additionally, its primary –OH allows formation of urethanes, carbonates and phosphate esters for plasticizers, lubricants, and coating/ink additives.
