Octadecyl sulfate sodium salt (CAS 1120-04-3)

Octadecyl sulfate sodium salt is a surfactant used in various research applications that require the formation and stabilization of micelles, emulsions, or colloidal systems. In analytical chemistry, it serves as an ion-pairing agent in methods such as high-performance liquid chromatography (HPLC) to help separate and analyze compounds that are otherwise difficult to detect or quantify. Due to its long hydrocarbon chain, Octadecyl sulfate sodium salt is also of interest in studies of surface chemistry phenomena, including adsorption, wetting, and surface tension properties. This surfactant is used in materials science to modify the surface properties of nanoparticles, facilitating their dispersion in aqueous and non-aqueous media for the creation of advanced materials with tailored functionalities. Furthermore, Octadecyl sulfate sodium salt is employed in the field of environmental research, particularly in the examination of soil remediation processes, where its ability to solubilize hydrophobic contaminants is valuable.
