Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in reactions involving palladium-catalyzed coupling processes. Its structure allows it to act as a ligand in catalytic systems, enhancing reaction efficiency and selectivity. Also employed in the development of novel phosphine-based catalysts for asymmetric synthesis, which are important in producing chiral molecules for drug manufacturing. Its amine and phosphine oxide functional groups enable dual reactivity, making it valuable in multi-step organic transformations.
