Sodium octyl sulfate Usage And Synthesis
Chemical Propertieswhite solid
UsesWetting, dispersing, and emulsifying agent.
UsesSodium octyl sulfate has been used in a study to assess selective enrichment of albumin in biological samples. It has also been used in a study to investigate the behavior of mixed solution of a glycerin-modified cationic surfactant and an anionic surfactant.
UsesSodium octyl sulfate (SOS) may be used as an ion-pairing reagent:
  • For the retention of catechols in reversed-phase high-performance liquid chromatography of catecholamines and their congeners.

  • For the separation of asymmetric dimethylhydrazine (ADMH) and its decomposition products using ion-pair chromatography.


DefinitionAnionic deter- gent, available commercially as a 35% solution.
General DescriptionSodium octyl sulfate is an anionic detergent and ion pairing reagent that is used in HPLC
Safety ProfilePoison by intraperitoneal route.Moderately toxic by ingestion. When heated todecomposition it emits toxic vapors of SOx.
