Description

1-Heptanesulfonic Acid Sodium Salt Monohydrate is a high-purity ion-pairing reagent and anionic surfactant widely used in analytical chemistry and pharmaceutical research. Its primary value lies in its ability to modify the retention and separation of basic compounds in reversed-phase liquid chromatography (HPLC). This makes it an essential material for analytical laboratories, pharmaceutical manufacturers, and research institutions focused on method development and quality control of active pharmaceutical ingredients (APIs).

Application

• Primary use as an ion-pairing reagent in Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) for the analysis of basic compounds, peptides, and pharmaceuticals.
• Critical component in the mobile phase for method development and validation in pharmaceutical quality control laboratories.
• Used as an anionic surfactant in capillary electrophoresis (CE) and related separation techniques.
• Employed in biochemical research for protein and nucleic acid analysis.
• Acts as a phase-transfer catalyst in certain organic synthesis applications.
• Potential use in the formulation of specialty detergents and cleaning agents for industrial processes.
