Product Overview
Tetrapropylammonium hydroxide (TPAOH) in a 20% aqueous solution is a high-purity quaternary ammonium base widely used in organic synthesis and analytical chemistry. This AR-grade reagent offers exceptional purity, ensuring reliable results in phase-transfer catalysis, where it facilitates the transfer of anions between immiscible phases. Its strong basicity and solubility in organic solvents make it a preferred choice for deprotonation reactions and the preparation of organometallic compounds. The aqueous form provides stability and ease of handling, reducing the risk of moisture-sensitive reactions. With a well-defined concentration, this solution eliminates the need for dilution, saving time in laboratory workflows. The analytical reagent grade guarantees minimal impurities, making it suitable for sensitive applications like ion-pair chromatography and the synthesis of fine chemicals. Store in a cool, dry place to maintain its stability and potency over extended periods.
FAQs
1. What is the shelf life of Tetrapropylammonium hydroxide 20% aqueous solution?
When stored unopened in a cool, dry place, this solution typically retains its stability for 12–24 months from the date of manufacture. Always check the label for the exact expiry date.
2. Can this solution be used directly in organic solvents without further purification?
The AR-grade purity ensures minimal impurities, allowing direct use in most organic solvents. However, for highly sensitive applications, additional drying or filtration may be recommended.
3. Is this product compatible with glass containers for long-term storage?
Yes, the aqueous solution is stable in glass containers, but ensure the container is tightly sealed to prevent absorption of atmospheric carbon dioxide, which can neutralize the base over time.
4. What precautions should be taken while handling this chemical?
As a strong base, it can cause severe skin and eye irritation. Always wear nitrile gloves, safety goggles, and a lab coat. Work in a fume hood to avoid inhalation of vapors.
5. Are there any alternatives to Tetrapropylammonium hydroxide for phase-transfer catalysis?
Alternatives include Tetrabutylammonium hydroxide (TBAOH) or Benzyltrimethylammonium hydroxide, though their reactivity and solubility profiles may differ based on the specific application.
