Rhodium, 5% on carbon is a useful reagent for the conversation of nitriles to primary amines and the hydrogenation of aromatic rings, pyridines, aldehydes and sugars. It is also used for the reduction of oximes to amines and for the reduction of nitrobenzene to phenylhydroxylamine using hydrazine hydrate as the hydrogen source.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
Rhodium, 5% on carbon is a useful reagent for the conversation of nitriles to primary amines and the hydrogenation of aromatic rings, pyridines, aldehydes and sugars. It is also used for the reduction of oximes to amines and for the reduction of nitrobenzene to phenylhydroxylamine using hydrazine hydrate as the hydrogen source.
Solubility
Insoluble in water.
Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, halogens, chlorine trifluoride and oxygen difluoride.
