Oleylamine is the organic compound with the formula C18H35NH2. It is an unsaturated fatty amine related to the fatty acid oleic acid. Although the pure compound is a colorless oil, typical commercial samples are yellowish and contain a few percent other fatty amines.
It has also been used in the laboratory in the synthesis of nanoparticles. It can function both as a solvent for the reaction mixture and as a coordinating agent to stabilize the surface of the particles.
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.
