Tri-n-octylphosphine oxide is a solvent used in the extraction of metals, especially uranium, zirconium and hafnium. It is also used as an auxiliary reagent in the solvent extraction of metals. It is also used to extract hydrogen bonding organic compounds. Further, it is useful as a capping ligand for the production of quantum dots, such as those consisting of cadmium selenide.
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.
