  • Applications

    3,7,11-Trimethyl-2,6,10-dodecatrienyl acetate (commonly called farnesyl acetate, CAS 4128-17-0) is a long-chain terpene ester of moderate volatility used across agriculture, fragrance, and research: in crop protection it serves as a semiochemical in insect pheromone blends for population monitoring, lure-based trapping, and mating disruption within integrated pest management, typically delivered via controlled-release dispensers (rubber septa, polymer fibers, microcapsules) to extend field life and minimize application rates; in perfumery it functions as a green–woody–floral note, as well as a carrier and fixative in fine fragrances, soaps, and personal care due to its oil solubility and stability; in cosmetics it helps odor masking and contributes to a smooth sensorial profile; in laboratories it is used as a GC–MS reference for isoprenoids and as a synthetic intermediate to farnesol and farnesyl derivatives (e.g., probes for protein prenylation studies); it can also act as a lipophilic carrier solvent for microencapsulated actives. Store protected from light and air (tight containers, inert headspace, optional antioxidants) to limit hydrolysis/oxidation that would diminish olfactory performance and lure efficacy.
