Product Overview
Tetrabutylammonium hydroxide (20% in methanol) is an AR-grade quaternary ammonium base widely used in organic synthesis and phase-transfer catalysis. This high-purity solution provides excellent solubility in organic solvents, making it ideal for reactions requiring strong, non-nucleophilic bases. The methanol solvent enhances reactivity while maintaining stability during storage. Its analytical reagent grade ensures minimal impurities, critical for accurate titration and sensitive applications. The solution’s consistent 20% concentration allows for precise dosing in laboratory protocols. Compatible with most glassware and standard lab equipment, this reagent is a versatile choice for researchers requiring reliable performance in alkaline conditions. Store in a cool, dry place away from moisture and incompatible materials to maintain its efficacy. The product is packaged in a leak-proof container to prevent contamination and ensure long-term stability.
FAQs
1. What is the shelf life of tetrabutylammonium hydroxide 20% in methanol?
When stored properly in a tightly sealed container at room temperature, the solution remains stable for 12–24 months. Avoid exposure to air or humidity to prevent degradation.
2. Can this solution be used as a phase-transfer catalyst in aqueous systems?
The methanol-based solution is primarily designed for organic solvents. For aqueous systems, consider adjusting the solvent ratio or using a water-compatible quaternary ammonium compound.
3. What precautions should be taken while handling this chemical?
Wear nitrile gloves, safety goggles, and a lab coat. Work in a fume hood due to methanol’s volatility and potential skin/eye irritation. Neutralize spills with dilute acid.
4. Is this product compatible with plastic containers for long-term storage?
Prolonged storage in plastic may lead to leaching or degradation. Use glass containers with PTFE-lined caps for optimal stability and to prevent contamination.
5. How does the AR grade differ from technical-grade tetrabutylammonium hydroxide?
AR grade ensures higher purity (≥98%) with tightly controlled impurities, suitable for analytical and research applications. Technical grade may contain trace contaminants, affecting reaction outcomes.
