Description

Application

PEPPSI-Ipr Catalyst is an air and temperature stable catalyst that is works well for Kumada-Tamao-Corriu (KTC), Negishi coupling, Suzuki coupling and Buchwald-Hartwig amination reactions. 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.
