Used as a ligand in catalytic processes, particularly in transition metal-catalyzed reactions, enhancing efficiency and selectivity. It is applied in organic synthesis, including cross-coupling reactions, to facilitate the formation of carbon-carbon and carbon-heteroatom bonds. Its sulfonic acid group provides solubility in aqueous media, making it suitable for environmentally friendly or biphasic catalytic systems. Additionally, it is employed in the development of pharmaceuticals and fine chemicals, where precise control over reaction pathways is critical. Its unique structure also makes it valuable in asymmetric catalysis, contributing to the production of chiral molecules.
