General description

ChemBeads glass beads coated with Grubbs Catalyst® M300.
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

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)
