Hydrogenation Catalysts and Ligands

We are proud to offer new catalysts for hydrogenation through our collaboration with Kanata Chemical Technologies.

DuPhos and BPE Ligands

Asymmetric hydrogenation reactions represent the ideal process for the commercial manufacture of single-enantiomer compounds, because of the ease by which these robust procedures can be scaled up and because of the low levels of byproducts generated in these asymmetric hydrogenations.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
