product description
Tetrabutylammonium bromide is an environmentally benign, non-volatile, non-flammable, non-corrosive, low-cost, commercially available ammonium salt with high thermal and chemical stability. In TBAB, tetrabutylammonium salt can dissolve in both aqueous as well as in organic solvents, which helps to transport the water-soluble anionic reactants into the organic phase. Moreover, molten TBAB was also employed as an efficient ionic liquid to carry out organic transformations under solvent-free conditions[1].

Product Usage
Tetrabutylammonium Bromide (TBAB for short), with CAS No. 1643-19-2 and chemical formula C₁₆H₃₆BrN, appears as white crystalline powder, easily soluble in solvents such as water, ethanol and acetone, and is a commonly used quaternary ammonium salt phase transfer catalyst. Its core application is in the field of organic synthesis. As an efficient phase transfer catalyst, it can effectively promote the reaction between aqueous and organic phases, accelerate the progress of nucleophilic substitution, redox, elimination and other reactions, greatly improve reaction rate and yield, and is widely used in fine chemical fields such as drug synthesis, spice preparation and dye synthesis. In the electrochemical field, it can be used as a supporting electrolyte for non-aqueous electrolytes to improve electrolyte conductivity. In addition, it is used as an ion-pair reagent in the field of chemical analysis to assist chromatographic separation, and is also used as an intermediate in organic synthesis and surfactant, serving as an indispensable special chemical raw material in fine chemical and electrochemical fields.
