General description

Oleic acid (OA) is a fatty acid. OA is widely used as a surfactant for the stabilization of magnetic nanoparticles synthesized by the traditional coprecipitation method. Monodisperse magnetite nanoparticles (diameter = 7 and 19nm) coated with oleic acid (OA) have been prepared.

Application

Oleic acid may be used in the preparation of 10-hydroxyoctadecanoic acid and methyl ester of 10-hydroxyoctadecanoic acid.

Other Notes

The article number 27728-6X1L-R will be discontinued. Please order the single bottle 27728-1L-R which is physically identical with the same exact specifications.
