What is Tetraethylammonium Bromide?
Tetraethyl ammonium bromide (TEAB) is a quaternary ammonium compound with the chemical formula of C8H20N+Br -, which is generally created as “Et4N+Br -” in chemical literature. It is made use of as the source of tetraethyl ammonium ion in pharmacology and also physiology research study, but also utilized in organic chemical synthesis.
Like tetraethyl ammonium chloride and also tetraethyl ammonium iodide, TEAB has been made use of as a tetraethyl ammonium ion source for many clinical and medicinal researches, which are described in even more detail under the product of tetraethyl ammonium chloride. In short, TEAB has been checked out medically as a result of its ganglion block qualities. Although it is currently primarily outdated as a drug, it is still made use of in physiological study because of its ability to obstruct K+channels in numerous tissues.
Ions and highly polar materials can be divided on a reversed-phase HPLC column by using ion-pair reagents as mobile stage additives. The purity of mobile phase additives is crucial to their effective application. Sigma-Aldrich provides a collection of superb customized reagents for the decision of anions (quaternary ammonium salts and also quaternary salts) and cations (alkane sulfonates).
Tetraethylammonium Bromide Uses
Tetraethyllammonium Bromide can be made use of as a tetraethyl ammonium ion source for numerous medicine research study. It also has the capability to obstruct K+networks in numerous cells.
Tetraethyl ammonium bromide can be made use of as polarographic evaluation reagent and also pesticide intermediate, and can be utilized for ion-pair chromatography to find gold, iridium, palladium, rhodium as well as ruthenium.

Application of Tetraethylammonium Bromide
Phase transfer drivers for organic synthesis, treating accelerators for polymer polymerization, organic electrolytes for digital industry, oilfield chemicals, molecular filter design templates, stage adjustment freezer products, high performance liquid chromatography evaluation reagents, surfactants, cleaning agents, adsorbents, oil displacement agents, etc.
- Tetraethyl ammonium bromide (TEAB) catalyzes the synthesis of thioesters via the oxidative combining of aldehydes or alcohols with thiols or disulfides.
- It is used together with o-iodobenzoic acid (IBX) as a stimulant for the oxidation of sulfides to sulfoxide as well as the oxidation of main formamide to mono-carbon demeronitrile.
- TEAB can likewise be used as artificial zeolite β Organic theme.
