Used primarily as an intermediate in organic synthesis, particularly in the preparation of esters and amides for applications in pharmaceuticals and lipid-based compounds. It is employed in the modification of biomolecules due to its long-chain fatty acid derivative structure, enabling incorporation into liposomes or lipid bilayers for drug delivery systems. Also utilized in the development of surfactants and emollients in cosmetic formulations, where its palmitoleoyl chain contributes to skin permeability and moisturizing properties. Its reactivity allows for efficient acylation in the synthesis of labeled lipids for metabolic studies.
