What is Sodium octanesulfonate?
Sodium octanesulfonate (CAS 5324-84-5) is an anionic surfactant.
Where is Sodium octanesulfonate used?
- Analytical and preparative chromatography: ion-pair reagent for HPLC separation of polar and ionic compounds
- Pharmaceutical quality control workflows
- Textile and leather processing: wetting and penetration agent improving dye uptake and chemical treatment uniformity
- Industrial and institutional cleaning: emulsification and soil release on hard surfaces and equipment
- Personal care: rinse-off formulations requiring controlled foaming and surfactant mildness
- Its eight-carbon alkyl chain balances hydrophobicity and water solubility for surface-active and ion-pairing functions.
Commercial specifications
- High-purity reagent and HPLC grades for analytical use; technical grade for industrial cleaning and textile processing
- Laboratory quantities to bulk industrial volumes
