Bromuro di tetraetilammonio

Descrizione:

Bromuro di tetraetilammonio (TEAB) è un sale di ammonio quaternario con la formula chimica C8H20BrN. È caratterizzato dalla sua apparente cristallina bianca ed è altamente solubile in acqua e solventi organici polari. Il TEAB è comunemente usato come catalizzatore di trasferimento di fase nella sintesi organica, facilitando il trasferimento di ioni tra fasi in reazioni che coinvolgono solventi immiscibili. Il composto presenta un alto grado di carattere ionico grazie alla presenza dell'ione di ammonio quaternario, che contribuisce alle sue proprietà di stabilità e solubilità. Inoltre, il TEAB può agire come fonte di ioni tetraetilammonio, spesso utilizzati in varie applicazioni elettrochimiche. È importante maneggiare il TEAB con cura, poiché può essere irritante per la pelle e gli occhi, e devono essere osservate le adeguate precauzioni di sicurezza durante il suo utilizzo. In generale, Bromuro di tetraetilammonio è un reagente versatile sia in contesti chimici accademici che industriali.

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.
