Perfluorononanoic acid: Standards & Products

Perfluorononanoic acid, or PFNA, is an organofluorine compound with the formula CF3(CF2)7CO2H. As the name implies it is the perfluorinated analogue of nonanoic acid, one of the perfluorinated carboxylic acids. As such, it is classified as a PFAS, a fluorosurfactant that has attracted attention as a persistent organic pollutant.
