Description
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.

Questions about XPhos, min. 97 %, 1 g, glass
What is this article?
XPhos, min. 97 %, 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
