Tetraethylammonium bromide (TEAB) is a quaternary ammonium salt. It has a central nitrogen atom surrounded by four ethyl groups and a bromide anion. It is usually a white crystalline solid and can dissolve in polar solvents such as water and some organic solvents. TEAB is well - known for its excellent phase - transfer catalytic ability. In many organic reactions, it can bridge the gap between immiscible phases (like the aqueous and organic phases). For example, in nucleophilic substitution reactions, it can transfer the nucleophilic reagent from the aqueous phase to the organic phase. This transfer significantly enhances the reaction rate and the yield of the desired products. The unique structure of TEAB, with its hydrophobic ethyl groups and hydrophilic ammonium center, allows it to interact with both polar and non - polar substances, making it a valuable tool in organic synthesis

Tetraethylammonium bromide (TEAB) is a quaternary ammonium salt.
It is a white crystalline solid at room temperature.
It is soluble in polar solvents such as water and some organic solvents like acetonitril-e.
Chemical synthesis
Tetraethylammonium bromide acts as a phase-transfer catalyst, enhancing reaction rate and selectivity in organic reactions like alkylation of active methylene compounds.
Serves as a starting material for making other quaternary ammonium salts.
Electrochemistry
Tetraethylammonium bromide is used as a supporting electrolyte in non-aqueous electrolytes for batteries and electrochemical sensors to ensure good conductivity.
Biological and pharmacological research
Tetraethylammonium bromide can block potassium ion channels in biological membranes for studying their roles, though its use in living systems needs caution due to toxicity.
