Description
Perfluorononane, a common liquid perfluoro-n-alkane, is recognized for its unique properties such as being biologically inert, immiscible with water, and having a low viscosity and surface tension. It is also a potent greenhouse gas, and concerns have been raised regarding the environmental and health hazards posed by its toxic decomposition products. The intramolecular electronic environment of perfluorononane has been studied using 13C and 19F NMR techniques, along with theoretical calculations of molecular orbitals.
Uses
Used in Polymer Photovoltaic Cells:
Perfluorononane is used as an interface material between the active and buffer layers to enhance the performance of polymer photovoltaic cells. Its unique properties contribute to improved efficiency and overall performance of these solar energy devices.
Used in Medical Imaging (Gastrointestinal Applications):
In the medical field, perfluorononane serves as selective and specific markers for monitoring gastric emptying and gastrointestinal (GI) transit times. This is achieved through the use of 27Al and 19F nuclear magnetic resonance (NMR) techniques, allowing for better understanding and diagnosis of various gastrointestinal conditions in both mice and humans.
Used as an Oral Contrast Agent:
Due to its biological inertness, immiscibility with water, and low viscosity and surface tension, perfluorononane is considered an ideal oral contrast agent for medical imaging. These properties make it suitable for various diagnostic procedures, enhancing the visualization of the gastrointestinal tract and aiding in the detection of potential issues.

Check Digit Verification of cas no
The CAS Registry Mumber 375-96-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 375-96:
(5*3)+(4*7)+(3*5)+(2*9)+(1*6)=82
82 % 10 = 2
So 375-96-2 is a valid CAS Registry Number.

THERMAL DECOMPOSITION OF PERFLUOROALKANESULFONYL FLUORIDES: THE PYROLYSIS OF PERFLUORO-n-OCTANE-1-SULFONYL FLUORIDE

, p. 377 - 386 (2007/10/02)
The preliminary data obtained from thermal decompositions of perfluoro-n-octane-1-sulfonyl fluoride in a continuous tubular-flow reactor are reported.The pyrolysis results in a radical reaction producing fluorocarbons, with high conversions and with yields depending on the experimental conditions.The reaction mixture composition also depends on the experimental conditions, so it is possible to obtain a prevalent formation of either light or heavy fluorocarbons.
