About Tetra Octyl Ammonium Bromide

Tetra Octyl Ammonium Bromide is a quaternary ammonium salt with the chemical formula C₃₂H₆₈BrN. It is a surfactant or a surface-active agent, which means it can lower the surface tension of a liquid and increase its spreading and wetting abilities. It is used in various applications, such as in the production of catalysts, as an organic surface coating agent, as a phase-transfer catalyst, and as a stabilizer for emulsions. Tetra Octyl Ammonium Bromide supplied in poly and glass bottles is also used in analytical chemistry as an ion-pairing reagent to improve the separation and analysis of compounds.
