Tetradecylsuccinic anhydride is primarily used as an intermediate in the synthesis of surfactants and lubricant additives. Its reactive anhydride group allows it to form esters or amides, making it valuable in producing compounds that improve the performance of industrial lubricants by enhancing their viscosity and thermal stability. Additionally, it is employed in the production of corrosion inhibitors, which protect metal surfaces in various industrial applications. Its hydrophobic alkyl chain contributes to its effectiveness in creating water-repellent coatings and surface treatments. In the polymer industry, it serves as a modifier to enhance the properties of resins and adhesives, improving their flexibility and adhesion.
