Potassium chloropalladite (Cat No.: M121188), typically represented as K₂PdCl₄, is a red-orange crystalline compound consisting of palladium(II) complexed with four chloride ligands and balanced by potassium cations. It serves as a precursor to various palladium catalysts, especially in cross-coupling reactions such as Suzuki, Heck, and Sonogashira. Soluble in water and polar solvents, it provides a convenient source of Pd(II) for forming active catalytic species. Widely used in organic synthesis, it plays a crucial role in assembling complex carbon–carbon and carbon–heteroatom bonds.
