Used as a palladium-based catalyst in cross-coupling reactions, particularly in Buchwald–Hartwig amination and Suzuki–Miyaura coupling. It enables efficient carbon–nitrogen and carbon–carbon bond formation, which is critical in synthesizing pharmaceuticals, agrochemicals, and functional materials. The methylamino and sulfonate groups enhance solubility and stability, improving catalytic activity under mild reaction conditions. Commonly applied in late-stage functionalization of complex molecules due to its tolerance of diverse functional groups.
