  • Applications

    The unsaturated C18 fatty alcohol (9E,12E)-octadeca-9,12-dien-1-ol (CAS 1577-52-2) is used primarily as an intermediate to make surfactants (via sulfation or ethoxylation) and long-chain esters for fragrance applications—such as acetate/propionate notes with fatty–green nuances—while its double bonds serve as handles for epoxidation, hydroformylation, or acrylate/urethane functionalization to build UV‑curable oligomers and resins; in petrochemical and materials contexts it acts as a modifier and comonomer to tune membrane fluidity, enable autoxidative crosslinking in alkyd coatings and inks, reduce friction and wear as a lubricant additive, and improve wetting/leveling due to its long hydrophobe; in agriculture and pest management, 18:2 alcohol/acetate derivatives with 9,12-diene motifs are formulated for insect pheromone lures and mating disruption, with this compound often serving as a GC/MS reference standard; additionally, it is a versatile building block in organic synthesis and in studies of lipid-mimetic assemblies and crystallinity control in bio-based fatty alcohol blends.
