77-7030 77-0425 77-0453
spacer

We offer a variety of photocatalysts, related kits for screening purposes, as well as ligands and precursors for photocatalyst synthesis. Many of these novel compounds have been applied to solar cell research, light emitting diode manufacturing (LED) and initiators for free radical polymerizations. More recently, these catalysts have been applied to a diverse group of organic transformations that have been difficult or even inaccessible previously.

spacer

For nearly 20 years, we've provided Buchwald ligands and precatalysts for both R&D and commercial applications. Buchwald ligands are used to make a variety of Buchwald precatalysts. These precatalysts are in turn used for a range of organic coupling transformations that offer advantages in terms of efficiency, activity and stability over traditional palladium catalysts.
