Tetrabutylammonium Bromide is a quaternary ammonium chemical compound, organic salt, and reaction auxiliary used in controlled industrial synthesis systems. Identified by CAS 1643-19-2, its bulky tetrabutylammonium cation exhibits strong ion‑pairing behavior and phase compatibility in heterogeneous reaction environments. In industrial chemical processing, it is commonly applied in phase transfer–assisted synthesis, where ionic species are transported between immiscible reaction phases under defined conditions. The material is supplied with competitive factory pricing, supports customized specifications, and is provided with complete MSDS, TDS, COA documentation for bulk supply.

FAQ - Technical & Supply Chain
-
Q:
Are tetrabutylammonium bromide and tetra‑n‑butylammonium bromide the same substance?
A: Yes. These names represent different naming conventions for the same quaternary ammonium salt and correspond to the same CAS‑registered substance. -
Q:
How does this compound function as a phase transfer catalyst?
A: Tetrabutylammonium Bromide operates by forming an ion pair with a reactant anion in the aqueous phase and transporting it into the organic phase, where the reaction can occur rapidly due to increased solubility and reactivity.
