Tetraethylammonium bromide

Description:

Tetraethylammonium bromide (TEAB) is a quaternary ammonium salt with the chemical formula C8H20BrN. It is characterized by its white crystalline appearance and is highly soluble in water and polar organic solvents. TEAB is commonly used as a phase transfer catalyst in organic synthesis, facilitating the transfer of ions across phases in reactions that involve immiscible solvents. The compound exhibits a high degree of ionic character due to the presence of the quaternary ammonium ion, which contributes to its stability and solubility properties. Additionally, TEAB can act as a source of tetraethylammonium ions, which are often utilized in various electrochemical applications. It is important to handle TEAB with care, as it can be irritating to the skin and eyes, and proper safety precautions should be observed during its use. Overall, tetraethylammonium bromide is a versatile reagent in both academic and industrial chemistry settings.

Tetraethylammonium bromide

CAS: 71-91-0

Tetraethylammonium bromide is an ionic liquid that has a low viscosity and high water solubility. It is used as an antimicrobial agent in the process of producing polymers, such as polyurethane. Tetraethylammonium bromide has been shown to be effective against a broad range of bacteria, including Bacillus subtilis and Escherichia coli. It has also been shown to have a protective effect on neurons by preventing neuronal death in response to oxidative stress. This protection may be due to its ability to increase the concentration of cytosolic Ca2+ ions, which are involved in neuronal survival pathways.
