Sodium perfluorononanoate

Description:
Sodium perfluorononanoate, with the CAS number 21049-39-8, is a perfluorinated compound that belongs to the class of perfluoroalkyl substances (PFAS). It is characterized by a long carbon chain, specifically containing nine carbon atoms fully fluorinated, which imparts unique properties such as high thermal stability, chemical resistance, and low surface tension. This compound is typically used as a surfactant and is known for its ability to repel water and oil, making it valuable in various applications, including coatings, textiles, and firefighting foams. Sodium perfluorononanoate is soluble in water and exhibits a high degree of persistence in the environment, raising concerns regarding its bioaccumulation and potential ecological impact. Its stability and resistance to degradation can lead to accumulation in living organisms and environmental matrices, prompting regulatory scrutiny. Overall, while it offers beneficial properties for industrial applications, the environmental and health implications of its use are significant considerations in its management and regulation.
