high stability to the oxidants (oxygen, nitric acid, hydrogen peroxide);
efficient extraction of metals from the acidic solutions (does not form salts with HCl, HNO3, H2SO4 at pH > 1);
low solubility in water;
moderate extractive capacity, higher selectivity and easier stripping;
the possibility of using as an additive to other extractants.
