Tri-n-octylamine, commonly known as TOA, is a highly important tertiary amine extractant. It is a colorless, viscous, oily liquid with a pungent odor.

It serves as an amine‑based extractant, exhibiting excellent purification performance for actinide elements such as thorium and uranium, and can also be employed to purify and separate rare metals, scarce and dispersed metal materials, and platinum‑group elements under various extraction systems. It is used in the production of phase‑transfer catalysts, plastic additives, and desulfurizing agents.

Tri-n-octylamine is classified as a Class 9 hazardous material, and a hazardous packaging certificate is required for export.
