What is Perfluorononanoic acid?
Chemical properties
Perfluorononanoic acid is a white crystalline powder or beige crystals. Perfluorononanoic acid has the ability to react with bases, oxidizing agents, and reducing agents. Upon decomposition, PFNA can form carbon oxides and hydrogen fluoride.
The Uses of Perfluorononanoic acid
Perfluorinated compounds (PFCs) are persistent in environments due to the high energy of C-F bond routes. PFNA may interfere in a toxic fashion on the immune system, liver, development, and endocrine systems.
The Uses of Perfluorononanoic acid
Perfluorinated compounds (PFCs) are persistent in environments due to the high energy of C-F bond. Being a persistent environmental pollutant, it can accumulate in human tissues via various exposure routes. PFNA may interfere in a toxic fashion on the immune system, liver, development, and endocrine systems.
Definition
ChEBI: A fluoroalkanoic acid that is nonanoic acid in which all of the hydrogens in the alkyl chain are replaced by fluorines.
