Scale-Up Guide: Buchwald-Hartwig Amination Reaction

All of the preformed catalysts used in the kit are air and moisture stable complexes in their commercially available form. Once activated by base under the reaction conditions they become sensitive to air. To best enable scale-up success, the use of standard Schlenk technique is recommended.

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