Potassium Tetrachloropalladate(II) CAS 10025-98-6

High-Purity Potassium Tetrachloropalladate(II) from Aure Chemical – Your Trusted Source

Potassium tetrachloropalladate(II), K₂[PdCl₄], CAS No. 10025-98-6, is a highly soluble anionic palladium(II) complex widely recognized as a convenient precursor in palladium-catalyzed transformations. Supplied by Aure Chemical as reddish-brown to dark brown crystalline powder with high palladium content (approximately 35–36% Pd), this air-stable salt readily provides [PdCl₄]²⁻ ions in aqueous or polar media. It serves as an efficient starting material for generating active Pd(0)/Pd(II) species in cross-coupling reactions (Suzuki, Heck, Sonogashira, Negishi), C–H activation, allylic substitution, and palladium nanoparticle synthesis, as well as for electroless palladium plating and organometallic complex preparation. Its superior water solubility compared to PdCl₂ makes it preferred for aqueous-phase catalysis, scale-up processes, and applications requiring minimal organic solvent use. Aure Chemical delivers precise Pd assay, low impurity profiles, and secure palladium sourcing to ensure batch consistency and optimal performance in pharmaceutical, fine chemical, and electronics industries worldwide.
