Description

Sodium octanesulfonate (CAS 5324-84-5 ) is an anionic surfactant used across industrial and specialty chemical applications. Its eight-carbon alkyl chain delivers a balance of hydrophobicity and water solubility that suits both surface-active and ion-pairing functions. Buyers source it as a process chemical for separation, formulation, and cleaning applications. In analytical and preparative chromatography, it functions as an ion-pair reagent for HPLC separation of polar and ionic compounds. This is particularly useful in pharmaceutical quality control workflows. Textile and leather processors use it as a wetting and penetration agent to improve dye uptake and chemical treatment uniformity across fiber substrates. In industrial and institutional cleaning formulations, it contributes to emulsification and soil release on hard surfaces and equipment. Personal care manufacturers incorporate it into select rinse-off formulations. These applications often require controlled foaming and surfactant mildness as process requirements. Sodium octanesulfonate is supplied as a white to off-white powder or as an aqueous solution, depending on the supplier. Standard grades include high-purity reagent and HPLC-grade material for analytical use, as well as technical grade for industrial cleaning and textile processing. Packaging ranges from laboratory quantities to bulk industrial volumes. Contact us for supply of Sodium octanesulfonate Request Quote
