Opis

Opis ogólny

A fourth generation (G4) Buchwald precatalyst on glass beads that is similar to the third generation (G3) precatalysts except that the amino group on the biphenyl backbone is methylated. This modification helps to prevent the limitations found when using the third generation precatalysts. It is air, moisture, and thermally-stable and shows good solubility in common organic solvents.

Zastosowanie

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 (900349)
