Used as a ligand in catalytic reactions, particularly in transition metal catalysis, to enhance the efficiency and selectivity of processes like hydrogenation and cross-coupling reactions. It is also employed in organic synthesis to stabilize reactive intermediates and improve yields. Additionally, it finds application in material science for the development of advanced polymers and coatings, where it acts as a stabilizer or additive to improve performance and durability. Its phosphine oxide group makes it useful in coordination chemistry for designing metal complexes with specific properties.
