Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for targeted cancer therapies. Its structure supports the formation of bioactive molecules due to the presence of both amine and phosphine oxide functional groups, which enhance binding selectivity and metabolic stability. Also employed in the preparation of ligands for transition metal catalysts in asymmetric synthesis, contributing to the production of chiral compounds in fine chemicals and agrochemicals. Shows potential in materials science for designing phosphorescent organic materials used in OLEDs due to its electron-transporting properties.
