Product Overview
Diethylzinc 1.5M solution in toluene is a highly reactive organometallic compound supplied in an AcroSeal® bottle to ensure maximum purity and minimal moisture exposure. This reagent-grade solution is stabilized in anhydrous toluene, making it ideal for applications requiring precise stoichiometry and controlled reactivity. The 1.5M concentration provides an optimal balance between reactivity and ease of handling, reducing the risk of violent reactions associated with neat diethylzinc. The AcroSeal® packaging features a resealable septum cap, allowing for multiple withdrawals without compromising the integrity of the remaining solution. This product is particularly valued for its consistency in batch-to-batch performance, with rigorous quality control ensuring low levels of metallic impurities and consistent molar concentration. The toluene solvent is carefully dried and distilled to meet laboratory standards, preventing side reactions that could arise from residual moisture or contaminants. For best results, store under inert gas and handle in a well-ventilated fume hood, as diethylzinc is highly pyrophoric and reacts violently with water or air.
FAQs
1. What precautions should be taken when handling Diethylzinc 1.5M solution?
Always handle under nitrogen or argon atmosphere using air-free techniques. Use flame-resistant lab wear and work in a fume hood with no ignition sources nearby. The solution is pyrophoric and reacts violently with water or oxygen.
2. Is this solution compatible with glass syringes for transfer?
Yes, but ensure the syringe is thoroughly dried and flushed with inert gas before use. Stainless steel needles are recommended over plastic to prevent corrosion or reaction with the solution.
3. What is the typical shelf life of Diethylzinc 1.5M in toluene when unopened?
When stored under inert gas at room temperature, the unopened solution remains stable for 12-18 months. Avoid temperature fluctuations and exposure to light to maintain potency.
4. Can this be used as a direct substitute for neat diethylzinc in reactions?
The 1.5M concentration allows for precise dosing but may require adjustment in reaction stoichiometry compared to neat diethylzinc. Test small-scale reactions first to confirm compatibility with your specific protocol.
5. How should empty containers be disposed of after use?
Rinse containers thoroughly with anhydrous solvent under inert conditions, then neutralize residues with isopropanol or a suitable quenching agent before disposal according to local hazardous waste regulations.
