Product Overview
Tetraethylammonium hydroxide (25% in water) is a quaternary ammonium base widely used in organic synthesis as a strong, non-nucleophilic base and phase-transfer catalyst. This reagent-grade solution offers precise alkalinity control in reactions where water solubility is required. The 25% concentration provides optimal balance between reactivity and handling safety, making it suitable for laboratory-scale applications. The solution remains stable under normal storage conditions but should be protected from moisture and carbon dioxide to prevent degradation. Its ionic nature facilitates homogeneous reactions in aqueous systems while maintaining compatibility with most organic solvents. The tetraethylammonium cation provides lipophilicity that enhances phase-transfer catalysis efficiency. This solution is particularly valuable in reactions requiring strong bases where sodium or potassium hydroxides might cause side reactions or solubility issues.
FAQs
1. What is the shelf life of this tetraethylammonium hydroxide solution?
The solution remains stable for 12-18 months when stored properly in tightly sealed containers at room temperature, protected from light and moisture.
2. Can this solution be used as a substitute for TEAOH pentahydrate?
Yes, this 25% aqueous solution can replace TEAOH pentahydrate in most applications, though you may need to adjust quantities to account for the different concentrations.
3. What precautions should be taken when handling this chemical?
Always wear appropriate PPE including gloves, goggles, and lab coat. Work in a fume hood as the solution is corrosive and emits ammonia-like fumes.
4. Is this solution compatible with glass containers for long-term storage?
Yes, the solution can be safely stored in glass containers as it doesn’t react with silica. Use amber glass bottles for extended storage periods.
5. What’s the typical pH range for this 25% TEAOH solution?
The solution typically has a pH between 13-14 due to its strong basic nature, similar to other concentrated hydroxide solutions.
