Perfluoroundecanoic acid

Description:
Perfluoroundecanoic acid (PFUnDA) is a perfluorinated carboxylic acid characterized by a long carbon chain consisting of eleven carbon atoms, fully fluorinated, which imparts unique properties. It is a colorless, odorless solid at room temperature and is known for its high thermal stability and resistance to chemical degradation. PFUnDA is hydrophobic and lipophobic due to the presence of fluorine atoms, making it insoluble in water but soluble in organic solvents. This compound is part of a larger class of perfluoroalkyl substances (PFAS), which are known for their persistence in the environment and potential bioaccumulation in living organisms. PFUnDA has been used in various industrial applications, including surfactants and coatings, but its environmental and health impacts have raised concerns, leading to increased regulatory scrutiny. Studies have suggested potential links to adverse health effects, prompting ongoing research into its behavior in the environment and its effects on human health. As a result, PFUnDA is subject to monitoring and regulation in many jurisdictions.
