TPABr

Tetrapropyl ammonium bromide, with the chemical formula C12H28BrN, is a white or pale yellow crystalline powder with strong hygroscopicity. It easily absorbs moisture in the air and gradually deliquescence. TPABr Cas:1941-30-6 is easily soluble in water and alcohol solvents, and this good solubility provides convenience for its reaction in solution. As a type of quaternary ammonium salt, in the structure of tetrapropylammonium bromide, four propyl groups are arranged in a tetrahedral pattern around the central nitrogen atom. Bromine ions act as counterions and are connected to the central cation through ionic bonds, forming a stable molecular structure.

Tetrapropylammonium bromide Cas:1941-30-6 has good surface activity and can form stable foam and emulsion in solution, so it is widely used in detergent, emulsifier and other fields. Its low toxicity and biodegradability also make it an important research direction for environmentally friendly surfactants.

In organic synthesis, Tetrapropylammonium bromide(TPABr) as a phase transfer catalyst can significantly improve the efficiency of heterogeneous reactions. Due to the ability of bromide ions in tetrapropylammonium bromide to exchange with other anions, it is also used as an ion exchanger.
