The Uses of Sodium octyl sulfate
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.
The Uses of Sodium octyl sulfate
Wetting, dispersing, and emulsifying agent.
The Uses of Sodium octyl sulfate
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.
What are the applications of Application
Sodium octyl sulfate is a useful chemical to study the selective enrichment of albumin in biological samples
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
