Verwenden

Tetraethylammonium Bromide, can be used as a source of tetraethylammonium ions for various pharmaceutical studies. It has also the ability to block K+ channels in various tissues.

Allgemeine Beschreibung

The use of ion-pairing reagents as mobile phase additives allows the separation of ionic and highly polar substances on reversed phase HPLC columns. The purity of mobile phase additives is of utmost importance to their successful application. Sigma-Aldrich offers an outstanding range of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) determination. All mobile phase additives are subject to rigorous testing with special emphasis on the requirements of modern reversed phase HPLC:

l?uterung methode

Recrystallise the bromide from EtOH, CHCl3 or diethyl ether, or recrystallise it from acetonitrile and dry it over P2O5 under reduced pressure for several days. It also recrystallises from EtOH/diethyl ether (1:2), EtOAc, water or boiling MeOH/acetone (1:3) or by adding an equal volume of acetone and allowing to cool. Dry it at 100o in vacuo for 12 days, and store over P2O5. [Beilstein 4 IV 332.]
