Product Overview
Tetraethylammonium bromide (TEAB) is a high-purity quaternary ammonium salt widely used in laboratory applications due to its excellent solubility in organic solvents and water. With a purity of 98%, this reagent serves as an efficient phase-transfer catalyst, facilitating reactions between compounds in immiscible solvents. Its stable ionic structure makes it ideal for electrochemical studies, where it functions as a supporting electrolyte, ensuring consistent conductivity without interfering with redox processes. The crystalline powder form allows for precise weighing and easy dissolution, making it a preferred choice for synthesis protocols requiring controlled reagent addition. Its low hygroscopicity ensures long-term stability under standard storage conditions, reducing the risk of degradation or moisture absorption. Whether used in organic synthesis, ion-pair chromatography, or as a template in supramolecular chemistry, this grade of tetraethylammonium bromide delivers reliable performance, minimizing side reactions and improving yield consistency. The absence of heavy metal impurities further enhances its suitability for sensitive applications, including pharmaceutical intermediate synthesis and material science research.
FAQs
1. What is the solubility of tetraethylammonium bromide in common solvents?
Tetraethylammonium bromide is highly soluble in water, methanol, ethanol, and acetone. It also dissolves well in polar aprotic solvents like dimethylformamide (DMF) and dimethyl sulfoxide (DMSO), making it versatile for various reaction media.
2. Can this compound be used as a supporting electrolyte in non-aqueous electrochemical cells?
Yes, its stable ionic nature and wide electrochemical window make it suitable for use as a supporting electrolyte in non-aqueous systems, particularly in organic solvents like acetonitrile or propylene carbonate.
3. Are there any known incompatibilities with other reagents?
Avoid combining it with strong oxidizing agents, as this may lead to decomposition. It is also incompatible with strong bases at elevated temperatures, which can cause Hofmann elimination.
4. How should tetraethylammonium bromide be stored to maintain its purity?
Store in a tightly sealed container in a cool, dry place, away from direct sunlight and moisture. Keeping it under inert gas (e.g., nitrogen) can further prevent degradation over extended storage periods.
5. What alternatives exist if tetraethylammonium bromide is unavailable?
Tetrabutylammonium bromide (TBAB) or tetraethylammonium chloride (TEAC) can serve as alternatives, though their solubility profiles and electrochemical properties may differ slightly, requiring adjustments in experimental conditions.
