1-Octanesulfonic Acid Sodium Salt（Cat No.:R031898）is an anionic surfactant and ion-pairing reagent commonly used in high-performance liquid chromatography (HPLC), particularly for the separation of basic or polar compounds. It appears as a white crystalline powder, soluble in water and organic solvents. With a hydrophobic octyl chain and a hydrophilic sulfonate group, it enhances retention and resolution of analytes on reversed-phase columns. This compound also serves in electrochemical analysis and surface treatments. Its dual functionality makes it essential in pharmaceutical analysis, environmental monitoring, and various biochemical and industrial applications.
