Disodium tetrachloropalladate (CAT: R023919) is a water-soluble palladium(II) salt commonly used as a precursor in homogeneous catalysis and nanoparticle synthesis. Comprising palladium coordinated with four chloride ligands and two sodium counterions, it serves as a convenient source of Pd²⁺ for cross-coupling reactions such as Suzuki–Miyaura, Heck, and Sonogashira. Its solubility in polar solvents allows for efficient incorporation into aqueous-phase catalysis, electroless plating, and organometallic complex formation. Na₂PdCl₄ is also used in the preparation of palladium-based sensors and functional materials. Its versatility and stability make it an essential reagent in academic and industrial synthetic chemistry.
