XPhos, min. 97 %, 1 g, glass

XPhos is a bulky monophosphine ligand offered at a minimum purity of 97 % for modern cross-coupling catalysis. With CAS number 564483-18-7 and empirical formula C₃₃H₄₉P, it has a molar mass of 476,72 g/mol. The ligand is valued in palladium-catalysed C–C and C–N bond-forming reactions, where its sterically demanding biarylphosphine scaffold supports high activity and broad substrate scope. Researchers use XPhos to generate active catalytic systems for challenging aryl and heteroaryl couplings under carefully controlled conditions. The defined molecular weight and purity level support reproducible ligand-to-metal ratios and reliable performance in both academic and industrial synthetic workflows that depend on well-characterised phosphine ligands.
