Perfluoroheptanesulfonic acid (PFHpS) （Cat No.:R035591）is a synthetic fluorosurfactant and a member of the perfluoroalkyl sulfonate family. Known for its exceptional stability and resistance to degradation, PFHpS is used in various industrial applications, including stain-resistant fabrics, firefighting foams, and non-stick coatings. Its persistence in the environment and potential bioaccumulation raise significant environmental and health concerns. Studies suggest that PFHpS can disrupt endocrine functions and pose risks to wildlife and human health. Consequently, its use is increasingly regulated and monitored to mitigate its environmental impact.
