[7] Minor impurities include oxygen-containing substances such as amides and nitroalkanes.

In the presence of acetic acid, oleylamin forms with DNA insoluble complexes with the radii of the particles equal 60–65 nm.

[12][13] It can function both as a solvent for the reaction mixture and as a coordinating agent to stabilize the surface of the particles.

[13] Oleylamine has an LD50 (Intraperitoneal) of 888  mg/kg in mice, however, note that it is listed as a level 3 health hazard on the NFPA diamond, so it should be handled with caution.

Oleylamine can be characterized using MS, HNMR, CNMR, IR, and Raman.
