Relax. Now your ligands will behave. A pioneering breakthrough, Eastman's BoPhoz™ chiral ligands provide the next generation of catalysts. Now chiral ligands no longer require elaborate protection from the atmosphere, because air doesn't degrade them, providing a long and robust shelf life.
Plus, they're more reliable: reactions are reproducible from run to run, because they don't degrade while being charged to your vessel. So if it's stability you need, then call someone who cares. Samples are available, just dial 1~800
