What is Perfluoroundecanoic acid?

Chemical properties

Perfluoroundecanoic acid exists as a colorless solid. Perfluoroundecanoic acid has the ability to react with oxidizing agents. Upon decomposition, PFUnA can form carbon oxides and hydrogen fluoride.

The Uses of Perfluoroundecanoic acid

Perfluoroundecanoic acid (PFUnA, perfluoro-n-undecanoic acid, henicosafluoroundecanoic acid) is an eleven-carbon compound in the perfluoroalkyl family of chemicals. Perfluoroundecanoic acid is used in a variety of applications, including in stain- and grease-proof coatings on food packages, furniture, upholstery, and carpet. Like many other perfluoroalkyl compounds, PFUnA persists in the environment due to its long carbon chain. Some research related to PFUnA has been conducted but additional inquiry is recommended for better understanding of how the chemical interacts with organisms and the environment.

The Uses of Perfluoroundecanoic acid

Perfluorotetradecanoic acid may be used as an analytical reference standard for the quantification of the analyte in water samples using a high-performance liquid chromatography technique.

Definition

ChEBI: A fluoroalkanoic acid that is perfluorinated undecanoic acid.
