In the chemical industry, understanding the precise properties and applications of key compounds is fundamental for innovation and efficient production. Tetraethylammonium Bromide (TEAB), a quaternary ammonium salt, stands out for its versatile chemical nature and its widespread utility across various sectors. From advanced organic synthesis to industrial formulations, TEAB offers unique advantages. This article, brought to you by NINGBO INNO PHARMCHEM CO.,LTD., a prominent chemical manufacturer and supplier, explores the essential chemical properties and uses of TEAB, guiding procurement professionals and researchers on how to effectively buy this compound.

Chemical Identity and Key Properties of TEAB

Tetraethylammonium Bromide (CAS Number: 71-91-0) is characterized by its chemical formula, C8H20BrN, and a molecular weight of 210.16 g/mol. As a white to almost white solid, it typically exhibits high water solubility and can be found in high-purity grades, often assaying ≥99.0%. These physical and chemical attributes are crucial for its diverse functional roles:

  • Ionic Nature: As a salt, TEAB dissociates into tetraethylammonium cations (Et4N+) and bromide anions (Br-), enabling its function in ionic reactions and as an electrolyte.
  • Polarity and Solubility: Its structure grants it solubility in polar solvents like water and lower alcohols, making it suitable for aqueous-phase reactions or for transferring ionic species into organic phases.
  • Thermal Stability: While specific decomposition points vary, TEAB generally possesses sufficient thermal stability for many industrial processes.
  • Reactivity: The bromide ion can act as a leaving group or nucleophile in certain reactions, while the tetraethylammonium cation can influence solubility and act as a counter-ion.

Diverse Industrial Applications of TEAB

The unique combination of its ionic nature, solubility, and reactivity makes TEAB a valuable asset in several key industries:

  • Phase Transfer Catalysis (PTC): This is perhaps one of TEAB's most significant applications. It effectively facilitates reactions between immiscible phases by transporting reactive ions into the organic phase, increasing reaction rates and yields in nucleophilic substitutions, oxidations, and more.
  • Pesticide and Agrochemical Intermediates: TEAB serves as a vital intermediate in the synthesis of various agrochemicals, contributing to the development of effective crop protection solutions.
  • Surfactants and Emulsifiers: Its amphiphilic nature allows TEAB to function as a surfactant, aiding in the stabilization of emulsions and dispersions in various industrial formulations.
  • Polarographic Reagent: In analytical chemistry, TEAB is used as a supporting electrolyte in polarography, providing conductivity and maintaining a stable potential for electrochemical analysis.
  • Disinfectants and Antistatics: Its quaternary ammonium structure also lends itself to applications as a disinfectant and an antistatic agent in polymers and other materials.
