  • Applications

    9-Decenoic acid (CAS 14436-32-9) is a straight-chain, unsaturated fatty acid broadly utilized in food, flavor and cosmetic industries as a mild fatty-sweet odorant and precursor for fragrant esters, as a flavor modifier in confectionery; in agriculture as a key intermediate for synthesizing insect pheromones used in biological pest control; in pharmaceuticals as a molecular scaffold for installing functional groups in the development of antifungal and antibacterial agents; in petrochemistry as a mono- or co-monomer for producing functional polymers, elastomers and surfactants; and in organic-chemistry research as a model substrate for metathesis, epoxidation and selective hydrogenation reactions.
