Sigma-Aldrich would like to congratulate Robert Grubbs, Richard Schrock, and Yves Chauvin on their research achievements leading to the 2005 Nobel Prize Award in chemistry! Metathesis catalyst technology has enriched the areas of drug discovery, flavors/fragrances, and polymers while leading scientists to discover new disconnections in synthetic organic chemistry. Through our association with Materia, we are proud to be the exclusive provider of Grubbs’ metathesis catalysts for research purposes.
