Tetraethylammonium bromide (TEAB) is a quaternary ammonium salt with the formula (C2H5)4NBr, used in various chemical and biological applications. It acts as a catalyst in organic synthesis, particularly for thioester formation via oxidative coupling of aldehydes or alcohols with thiols. TEAB is also widely used in neuroscience and pharmacology research to block potassium channels in neurons, aiding in the study of ion channel function. Additionally, it serves as a phase transfer catalyst and in the synthesis of other quaternary ammonium salts, and for the development of electrolytes. 
 

Industrial Uses

1. Performance Chemicals

  • Phase transfer catalyst: Tetraethylammonium bromide (TEAB) is a versatile reagent used in chemical synthesis, primarily as a phase-transfer catalyst and in various organic reactions. It facilitates reactions between compounds in different phases, like water and an organic solvent, by transferring reactants across the interface.
  • Oxidative Coupling: TEAB catalyzes the reaction between aldehydes or alcohols with thiophenols or disulfides to form thioesters. 
  • Alkylation Reactions: It's used to introduce quaternary ammonium groups into molecules. 
  • Sulfoxide Synthesis: TEAB, along with o-iodoxybenzoic acid (IBX), can oxidize sulfides to sulfoxides.

2. Pharmaceuticals

  • Ion Channel Research: TEAB is a known blocker of potassium channels, including those found in neurons and other cells. By blocking these channels, researchers can investigate the role of these channels in various cellular processes, including nerve impulse transmission and muscle contraction.
  • Phase-Transfer Catalyst: TEAB acts as a phase-transfer catalyst in the synthesis of some pharmaceutical compounds. In organic chemistry, phase-transfer catalysts facilitate reactions between compounds that are not soluble in the same solution.
