Perfluorononane

Perfluorononane is a common liquid perfluoro-n-alkane. It is a potent greenhouse gas and environment and health hazards posed by its toxic decomposition products have been evaluated.[1] Perfluorononane is reported as an ideal oral contrast agent since it is biologically inert, immiscible with water, and also has a low viscosity and surface tension.[2] Intramolecular electronic environment of perfluorononane using ¹³C and ¹⁹F NMR techniques in combination with theoretical calculations of molecular orbitals has been reported.[3]

Perfluorononane may be employed in the interface between active and buffer layer to improve the performance of polymer photovoltaic cells.[4] It may be employed as selective and specific markers for monitoring the gastric emptying and gastrointestinal (GI) transit times in mice and humans by using ²⁷Al and ¹⁹F nuclear magnetic resonance (NMR).[5]
