Oleylamine [112-90-3]

 

Oleylamine is an organic compound with a molecular formula C₁₈H₃₅NH₂. It is an unsaturated fatty amine related to the fatty acid oleic acid. The pure compound is a clear and colorless liquid. Commercially available oleylamine reagents vary in color from clear and colorless to varying degrees of yellow due to impurities. The major impurities include trans isomer (elaidylamine) and other long chain amines with varying chain lengths. Minor impurities include oxygen-containing substances such as amides and nitroalkanes.
 

Uses

Commercially, it is mainly used as a surfactant or precursor to surfactants.

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. It can also coordinate with metal ions, change the form of metal precursor and affect the formation kinetics of nanoparticles during the synthesis.
