| Sodium octyl sulfate Usage And Synthesis |
| Chemical Properties | white solid |
| Uses | Sodium 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. |
| Uses | Wetting, dispersing, and emulsifying agent. |
| Uses | Sodium 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. |
| Definition | Anionic deter- gent, available commercially as a 35% solution. |
| General Description | Sodium octyl sulfate is an anionic detergent and ion pairing reagent that is used in HPLC |
| Safety Profile | Poison by intraperitoneal route.Moderately toxic by ingestion. When heated todecomposition it emits toxic vapors of SOx. |
