MSE PRO™ 2-(Dicyclohexylphosphino)-2',4',6'-triisopropylbiphenyl (XPhos), 98% Purity

MSE PRO™ 2-(Dicyclohexylphosphino)-2',4',6'-triisopropylbiphenyl (XPhos) is a highly effective ligand in Pd-catalyzed amination and amidation reactions of aryl sulfonates. XPhos serves as a crucial reagent in the production of novel [1,2,4]triazolo[4,3-a]pyrazine derivatives, which have potential as selective c-met inhibitors with improved pharmacokinetic properties.
