General description

Sodium octyl sulfate is an anionic detergent and ion pairing reagent that is used in HPLC

Application

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.
