Perfluoroundecanoic acid Usage And Synthesis

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.

Uses

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.

Uses

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.

General Description

Perfluoroundecanoic acid belongs to the class of persistent perfluorinated compounds, found in environmental and biological samples. They are used in various commercial applications such as in firefighting foams, detergents, insecticides, paper, food containers as well as to produce photographic films and manufacture fat- and water-resistant fabrics, etc.
