Used as a catalyst precursor in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Heck reactions. It serves as a source of palladium(0) when reduced in situ, enabling the formation of carbon-carbon bonds in pharmaceuticals, agrochemicals, and fine chemicals. Its ammine ligands stabilize the palladium in solution, improving handling and reactivity under mild conditions. Also employed in electroless palladium plating baths for printed circuit boards and surface finishing in electronics due to its ability to release active palladium species for metal deposition.
