Used primarily as an intermediate in organic synthesis, particularly in the production of fragrances and flavor compounds due to its fatty acid chloride nature. It is employed in the preparation of amides and esters, which are key structures in pharmaceuticals and agrochemicals. Its long aliphatic chain makes it useful in modifying the lipophilicity of molecules, enhancing membrane permeability in drug design. Also utilized in polymer chemistry for introducing long-chain acyl groups to modify polymer properties such as flexibility and hydrophobicity.
