Used as a selective extractant in hydrometallurgical processes, particularly for the separation and recovery of valuable metals such as copper, nickel, and cobalt from aqueous solutions. Its molecular structure enables efficient complexation with metal ions, making it effective in solvent extraction operations within mining and recycling industries. Exhibits good phase separation and low solubility in water, which enhances recovery efficiency and reduces reagent loss. Also applied in the purification of rare earth elements due to its stability under acidic conditions and high selectivity.
