Nonafluoro-1-butanesulfonic acid (Cat No.:R058089) is a perfluorinated sulfonic acid known for its strong acidity, chemical stability, and hydrophobicity. It features a fully fluorinated four-carbon chain terminated by a sulfonic acid group, making it a potent acid and an effective ion-exchange medium. NFBSA is used as a catalyst, fluorinating agent, and intermediate in the synthesis of fluorinated compounds, including surfactants and specialty polymers. Due to its persistence in the environment and potential bioaccumulation, its use is monitored under environmental regulations. Its high thermal and chemical resistance make it valuable in demanding industrial applications.
