General description

rac-BINAP-Pd-G3 ChemBeads are a third generation (G3) Buchwald precatalyst on glass beads. It is an air, moisture and thermally-stable precatalyst and is highly soluble in a wide range of common organic solvents. It has long life in solutions. rac-BINAP-Pd-G3 ChemBeads are an excellent reagent for palladium catalyzed cross-coupling reactions. Some of thier unique features include lower catalyst loadings, shorter reaction time, efficient formation of the active catalytic species and accurate control of ligand: palladium ratio, relative to earlier generations of Buchwald precatalysts.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Greener Chemistry. ChemBeads are advanced solid-coated beads for high-throughput experimentation in various chemical applications. They enable precise dispensing of solid reagents, allowing researchers to conduct reactions with minimal material use, thus supporting waste prevention and catalysis principles while ensuring accuracy and reproducibility. This technology enhances efficiency and streamlines experimental processes in chemistry. Click here for more information.

Application

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.For general uses, product is also available in powdered form (804967)
