Description

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.
