  • Applications

    (Z)-hexadec-11-enoic acid is a 16-carbon unsaturated fatty acid with a cis double bond at carbon 11, CAS number: 2416-20-8, commonly used as an intermediate in the synthesis of esters and other oleochemical derivatives. In industrial practice it is converted into compounds serving several sectors: polymers/plastics as a feedstock for polyesters and related polymers; coatings/inks through alkyd or other resin formulations; lubricants and plasticizers by esterification to improve flexibility and low-temperature performance; cosmetics/personal care as a precursor for surfactants or emollient esters; and fragrance and flavor sectors as a building block for fragrance ingredients. Its exact applications depend on formulation, regulatory constraints, and local limits.
