Product Overview

• TBAB, or Tetrabutylammonium Bromide, is a quaternary ammonium salt widely used as a phase-transfer catalyst across organic synthesis, pharmaceutical, and agrochemical manufacturing. It appears as a white, crystalline, hygroscopic solid with good solubility in water and most polar organic solvents. Its unique amphiphilic-adjacent structure, combining a bulky, lipophilic tetrabutylammonium cation with a bromide counter-ion, enables it to facilitate reactions between reagents located in immiscible aqueous and organic phases. Procorbay International supplies high-purity TBAB serving as a premier phase-transfer catalyst for chemical manufacturers requiring improved reaction efficiency in two-phase synthesis systems.
• TBAB is manufactured through the quaternization reaction of tributylamine with n-butyl bromide under controlled conditions, followed by purification and crystallization to achieve the required high-purity specification. Procorbay sources TBAB from established specialty quaternary ammonium manufacturers with consistent quality control over purity, moisture content, and bromide-content specifications.
• Industrially, TBAB's primary and most significant application is as a phase-transfer catalyst (PTC), a role in which it dramatically improves reaction rates and yields in two-phase (aqueous-organic) synthesis reactions by shuttling reactive anions across the phase boundary, enabling reactions that would otherwise proceed slowly or inefficiently due to reagent immiscibility. This property has made it indispensable across pharmaceutical active ingredient synthesis, agrochemical active ingredient manufacturing, and various fine chemical and dye synthesis processes, where it enables milder reaction conditions, reduced solvent use, and improved overall process economics compared to alternative synthesis approaches. It also finds application as an electrolyte component in certain electrochemical and battery research applications, leveraging its ionic conductivity properties.
• Given its critical role in improving synthesis efficiency across pharmaceutical, agrochemical, and fine chemical manufacturing, Procorbay maintains consistent, high-purity TBAB supply to serve process chemists and synthesis operations requiring reliable catalytic performance.
