Used as an intermediate in the synthesis of surfactants and emulsifiers, particularly in agrochemical formulations and industrial detergents. Its ether-acid structure enhances solubility and stability in both aqueous and organic systems, making it valuable in coupling reactions to produce ester or amide derivatives for specialty chemicals. Also employed in the development of lubricant additives and corrosion inhibitors due to its ability to chelate metal ions and improve surface activity.
