Product Overview
Tetraethylammonium hydroxide (TEAOH), supplied as a 20 wt.% aqueous solution, is a quaternary ammonium base widely used in organic synthesis and phase-transfer catalysis. This solution provides a strong, non-nucleophilic base that facilitates reactions requiring deprotonation or anion stabilization without interfering side reactions. The 20% concentration ensures optimal solubility and reactivity while maintaining stability during storage. Its high purity minimizes impurities that could affect experimental outcomes, making it suitable for sensitive applications. The aqueous form simplifies handling and dosing, reducing the need for additional solvents. Compatible with most organic solvents, TEAOH is particularly effective in biphasic systems where it enhances reaction rates by improving mass transfer. Store in a cool, dry place, away from incompatible substances like strong acids or oxidizing agents, to preserve its efficacy. This solution is a reliable choice for laboratories requiring consistent performance in base-catalyzed processes.
FAQs
1. What is the shelf life of tetraethylammonium hydroxide solution?
When stored properly in a tightly sealed container at room temperature, the solution remains stable for up to 24 months. Avoid exposure to air and moisture to prevent degradation.
2. Can this solution be used with non-polar solvents?
While primarily water-soluble, tetraethylammonium hydroxide can be paired with polar organic solvents like methanol or acetone for specific applications. Test compatibility for your reaction conditions.
3. Are there safer alternatives for less hazardous applications?
For milder basic conditions, consider tertiary amines like triethylamine or inorganic bases like potassium carbonate, though they may not offer the same phase-transfer capabilities.
4. How should spills of this solution be handled?
Neutralize spills with a dilute acid solution (e.g., acetic acid or hydrochloric acid), then absorb with inert material like sand or vermiculite. Dispose of waste according to local regulations.
5. Is this solution compatible with glassware?
Yes, it can be safely stored and used in standard borosilicate glass containers. Avoid prolonged contact with metals like aluminum or zinc to prevent corrosion.
