Tetrabutylammonium bromide CAS 1643-19-2

Tetrabutylammonium bromide, also known as tetra-n-butylammonium bromide; Tetra-n-butylammonium bromide; TBAB is an organic salt with the molecular formula C ₁₆ H ∝₆ BrN. The pure product is a white crystal or powder, with deliquescence and a special odor. It is stable at room temperature and atmospheric pressure. Soluble in water, alcohol, and acetone, slightly soluble in benzene. Toxic, commonly used as an intermediate in organic synthesis, Phase Transfer Catalyst, and ion pair reagent. Tetra-n-butylammonium bromide Cas: 1643-19-2, EINECS: 216-699-2;Tetrabutylammonium bromide Cas: 1643-19-2 can be used as an ion pair reagent for the synthesis of penicillin, sulbactam, etc; It is also an effective phase transfer catalyst. The commonly used ratio in organic synthesis is 0.003 times the molar ratio of the raw materials; The core principle of tetrabutylammonium bromide as a phase transfer catalyst is to enable two substances that were originally immiscible to "work together". This type of reaction is common in mixed systems of water and organic solvents, such as water and chloroform, water and toluene. After the two liquids are separated into layers, the reactants are trapped on one side each. At this point, tetrabutylammonium bromide acts like a courier, carrying anions from the aqueous phase across the interface to work in the organic phase.
