Bis(2,4,4-trimethylpentyl)phosphinic acid Chemical Properties, Uses, Production

Uses

Diisooctylphosphinic Acid functions as a surface passivating ligand in the synthesis of magic-sized cadmium selenide and cadmium telluride nanocrystals.

Uses

Diisooctylphosphinic acid (DiOPA) may be used in the following studies:

As the surface passivating ligand in the synthesis of magic-sized CdSe and CdTe nanocrystals.
As extractant in the extraction of Indium(III) from sulfate solutions.
As ligand to investigate the solubility of four copper ligand systems in supercritical CO₂.
As acid ligand for the Supercritical fluid extraction (SFE) of divalent metals (Zn²⁺, Cu²⁺, Pb²⁺, Cd²⁺ and Cr³⁺) from sand and fly ash using CO₂.

General Description

Diisooctylphosphinic acid is an organophosphorous acid.
