Product Overview
Diethylaluminium iodide (0.9M solution in toluene) is a highly reactive organoaluminium compound designed for specialized applications in organic and organometallic synthesis. The AcroSeal® packaging ensures maximum protection against air and moisture, preserving the reagent’s integrity for consistent performance in sensitive reactions. This solution offers precise molar concentration (0.9M) in anhydrous toluene, a non-polar solvent that enhances solubility and reactivity while minimizing side reactions. The compound’s strong Lewis acidity and alkylating properties make it ideal for use as a catalyst or co-catalyst in polymerization, hydroalumination, and carbon-carbon bond formation. Its controlled stoichiometry and high purity reduce variability in experimental outcomes, ensuring reproducibility in research and development workflows. The toluene solvent is rigorously dried and distilled to meet stringent lab standards, further supporting the reagent’s stability during storage and handling. For labs requiring reliable organometallic reagents, this solution balances reactivity with ease of use, eliminating the need for in-house dilution or purification.
FAQs
1. What is the shelf life of Diethylaluminium iodide 0.9M solution in toluene?
The solution remains stable for 12–18 months when stored unopened in its original AcroSeal® packaging under inert conditions (e.g., nitrogen or argon). Always check the label for the exact expiration date and avoid exposure to air or moisture.
2. Is this solution compatible with glassware, or should I use specific materials?
Diethylaluminium iodide reacts with protic surfaces, so use oven-dried glassware or PTFE-lined containers. Avoid plastic or rubber stoppers, as they may degrade or leach contaminants. Schlenk techniques or glove boxes are recommended for handling.
3. Can I substitute this for Diethylaluminium chloride in my reaction?
While both are organoaluminium reagents, the iodide variant exhibits different Lewis acidity and nucleophilicity. Substitution may alter reaction rates or selectivity. Test compatibility with your specific protocol or consult literature for comparable systems.
4. How should I dispose of unused or expired Diethylaluminium iodide solution?
Neutralize the solution carefully with a slow addition of isopropanol or ethanol in a well-ventilated fume hood, followed by dilution with water. Dispose of the resulting waste as hazardous chemical waste according to local regulations (e.g., incineration or licensed treatment facilities).
5. Why does the solution appear cloudy or form precipitates over time?
Cloudiness or precipitation typically indicates moisture contamination or partial decomposition. Ensure the container is tightly sealed under inert gas. If observed, avoid using the solution, as impurities can compromise reaction outcomes. Store in a desiccator or glove box for long-term stability.
