Description

1-Octanesulfonic Acid, Sodium Salt, Monohydrate is a high-purity, white crystalline powder widely used as an ion-pairing reagent and surfactant in analytical and industrial chemistry. Its primary value lies in its ability to modify selectivity and enhance the separation of hydrophobic compounds in reversed-phase liquid chromatography (HPLC). This product is essential for analytical laboratories, pharmaceutical R&D, and chemical manufacturing sectors requiring precise chromatographic analysis or specialized anionic surfactants.

Application

• Ion-Pairing Reagent for HPLC: Critical for improving the separation and peak shape of basic drugs, peptides, and other ionic analytes in reversed-phase chromatography.
• Pharmaceutical Analysis: Used in the development and quality control of active pharmaceutical ingredients (APIs) to ensure purity and compliance with pharmacopeial standards.
• Biochemical Research: Employed in protein purification and the analysis of biomolecules due to its surfactant properties.
• Chemical Synthesis: Serves as an intermediate or catalyst in organic synthesis reactions.
• Electrolyte Additive: Potential use in electrochemical applications and battery research.
• Detergent & Surfactant Formulations: Used in specialized industrial cleaning and emulsification processes.
