Tetra Ethyl Ammonium Bromide, Colour : White

Tetraethylammonium bromide (TEAB) is a quaternary ammonium salt characterized by the chemical formula (C2H5)4NBr. It appears as a white crystalline solid that is soluble in polar solvents such as water and ethanol. TEAB serves primarily as a phase transfer catalyst in organic synthesis, facilitating the transfer of ions or reactants between immiscible phases. Its amphiphilic properties enable efficient transportation of polar molecules across liquid-liquid interfaces, enhancing reaction rates and yields in chemical processes. TEAB is also employed as an electrolyte additive in batteries and as a surfactant in various industrial applications. Due to its stability and relatively low toxicity, TEAB is favored in research laboratories and industrial settings where phase transfer catalysis is integral to improving reaction efficiency and achieving desired product outcomes.
