Used as an intermediate in organic synthesis, particularly in the preparation of fatty acid derivatives and surfactants. It is employed in the modification of polymers to improve water repellency and surface properties. Also utilized in the development of lubricants and release agents due to its thermal stability and ability to form hydrophobic coatings. In pharmaceutical and cosmetic formulations, it serves as an acylating agent for the production of esters and amides with emollient properties. Its reactivity makes it suitable for introducing stearoyl groups in various chemical reactions, enhancing the lipophilicity of active compounds.
