Used as a selective solvent in nuclear fuel reprocessing, particularly in the extraction of actinides such as uranium and plutonium from spent nuclear fuel. It serves as a key component in advanced partitioning processes due to its high radiation stability and low water solubility. Its molecular structure enables efficient metal ion complexation, making it suitable in liquid-liquid extraction systems. Also investigated as a potential alternative to traditional organophosphorus extractants because of its favorable degradation profile and reduced formation of secondary waste.
