Product Overview
Tetraethylammonium hydroxide (TEAOH) 10% in water is a quaternary ammonium base widely used in laboratory settings for its strong basic properties and solubility in organic solvents. This aqueous solution contains 10% (w/v) of the hydroxide salt dissolved in deionized water, providing a stable and easy-to-handle reagent for various chemical processes. The compound acts as an effective phase transfer catalyst, facilitating reactions between water-soluble and organic-soluble reactants by transporting anions across phase boundaries. Its high basicity (pKa ~10.75) makes it particularly useful for deprotonation reactions, while the tetraethylammonium cation provides solubility in both polar and nonpolar solvents. The solution is prepared using high-purity starting materials to ensure minimal impurities, with typical metal ion content below 5 ppm. The 10% concentration offers a balance between reactivity and ease of handling, allowing precise dosing in synthetic procedures. The product is packaged in HDPE bottles with tamper-evident seals to maintain stability during storage and transportation. For optimal performance, the solution should be stored at room temperature and protected from moisture and carbon dioxide to prevent degradation of the hydroxide content.
FAQs
1. What is the shelf life of tetraethylammonium hydroxide 10% solution?
The solution typically maintains its specified concentration for 12 months when stored properly in tightly sealed original containers at room temperature. Over time, the hydroxide content may gradually decrease due to reaction with atmospheric carbon dioxide.
2. Can this solution be used with halogenated solvents?
Yes, tetraethylammonium hydroxide is compatible with most halogenated solvents like dichloromethane and chloroform, making it suitable for phase transfer catalysis applications involving these solvents.
3. What alternatives exist for this product?
Tetrabutylammonium hydroxide (TBAOH) solutions offer similar properties with slightly different solubility profiles. For solid bases, potassium tert-butoxide or sodium hydroxide may be considered, though they lack the phase transfer capabilities.
4. How should this solution be disposed of?
The solution should be neutralized with a suitable acid before disposal according to local chemical waste regulations. The quaternary ammonium component requires proper treatment as it may have environmental persistence.
5. Does this solution contain any stabilizers or preservatives?
This product is supplied without added stabilizers or preservatives. The 10% concentration in water provides inherent stability under recommended storage conditions.
