Tetraoctylammonium (bromide)

Tetraoctylammonium bromide (TOAB) is a quaternary ammonium salt consisting of a positively charged tetraoctylammonium cation and a negatively charged bromide anion. This compound is commonly used as a phase transfer catalyst in organic chemical reactions, facilitating the transfer of reactants between immiscible phases. It is also used as a surfactant and dispersant in various industrial applications, for example in the production of coatings, adhesives and polymers. Additionally, Tetraoctylammonium bromide has been investigated for potential applications in energy storage devices and as an antimicrobial agent.
