Description
Sodium 1-octanesulfonate (CAS 5324-84-5) is an anionic surfactant supplied under trade names including NAS 8RF, Bio-Terge PAS 8, Bio-Terge PAS 8SF, IPC B8, and IPC-ALKS-8. It carries no E-code designation and is classified under HS code 29041000.
In ion-pair chromatography, it acts as a mobile phase modifier, pairing with positively charged analytes to improve retention and separation on reversed-phase columns. In textile and leather processing, its sulfonate head group adsorbs onto fiber surfaces, reducing interfacial tension and enabling uniform dye penetration and soil removal. It also functions as a stabilizer in formulations where it suppresses oxidative degradation.
Sodium 1-octanesulfonate is available as a crystalline powder in standard and sulfate-free (SF) grades, the latter meeting stricter purity requirements for analytical and personal care applications. The substance is registered under REACH and suppliers typically offer documentation supporting GMP-compliant procurement. Packaging formats commonly include 25 kg fiber drums.
