Brometo de tetraetilamônio

Descrição:

Brometo de tetraetilamônio (TEAB) é um sal de amônio quaternário com a fórmula química C8H20BrN. É caracterizado por sua aparência cristalina branca e é altamente solúvel em água e solventes orgânicos polares. O TEAB é comumente usado como um catalisador de transferência de fase na síntese orgânica, facilitando a transferência de íons entre fases em reações que envolvem solventes imiscíveis. O composto exibe um alto grau de caráter iônico devido à presença do íon de amônio quaternário, que contribui para suas propriedades de estabilidade e solubilidade. Além disso, o TEAB pode atuar como uma fonte de íons tetraetilamônio, que são frequentemente utilizados em várias aplicações eletroquímicas. É importante manusear o TEAB com cuidado, pois pode ser irritante para a pele e os olhos, e as precauções de segurança adequadas devem ser observadas durante seu uso. No geral, Brometo de tetraetilamônio é um reagente versátil em ambientes de química acadêmica e industrial.

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.
