Used as a ligand in transition metal catalysis, particularly in palladium-catalyzed cross-coupling reactions. It enhances catalytic activity and selectivity in transformations such as Suzuki-Miyaura and Heck reactions. Its bidentate structure stabilizes metal centers, improving catalyst longevity and efficiency under mild reaction conditions. Also employed in homogeneous catalysis for fine chemical and pharmaceutical synthesis due to its electron-donating properties and steric profile.
