Sodium tetrachloropalladate(II) CAS 13820-53-6

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

Sodium tetrachloropalladate(II), Na₂[PdCl₄], CAS No. 13820-53-6, is a highly soluble anionic palladium(II) complex widely used as a convenient water-soluble precursor in palladium chemistry. Supplied by Aure Chemical as reddish-brown to dark brown crystalline powder or hydrated solid with high palladium content (approximately 36–37% Pd), this air-stable salt readily dissociates in aqueous or polar media to provide [PdCl₄]²⁻ ions. It serves as an efficient starting material for preparing palladium precatalysts employed in cross-coupling reactions (Suzuki, Heck, Sonogashira), C–H activation, allylic substitution, and palladium nanoparticle synthesis, as well as for electroless palladium plating and organometallic complex formation. Its excellent solubility and controlled reactivity make it preferred over anhydrous PdCl₂ in aqueous-phase processes and scale-up applications in pharmaceuticals, fine chemicals, and electronics. Aure Chemical ensures precise Pd assay, low impurity levels, and secure palladium sourcing to deliver reproducible performance for industrial and research use worldwide.
