General description

ChemBeads glass beads coated with Grubbs Catalyst® M300.

Application

Metathesis: Ruthenium-Based Metathesis Catalysts Labile pyridine ligands result in a very fast initiator (even at 0 °C). Effective in cross metathesis of acrylonitrile. Also effective in RCM and the ROMP production of block copolymers and polymers with narrow PDIs

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 larger scale uses, product also available in powdered form (682330)
