Primarily used as a solvent extractant in the separation and purification of metals, particularly in the nuclear industry for the extraction of uranium and plutonium from spent nuclear fuel. It is also employed in hydrometallurgical processes for the recovery of rare earth elements and other valuable metals from ores and industrial waste. Additionally, it finds application in the formulation of specialty chemicals and as a stabilizer in certain industrial processes. Its high selectivity and efficiency make it a valuable component in advanced extraction technologies.
