Product Overview
Diethyl ether, 99.5% extra dry and stabilized with AcroSeal®, is a high-purity solvent designed for critical laboratory applications where minimal moisture content is essential. The extra dry grade ensures ultra-low water levels, making it ideal for moisture-sensitive reactions and processes. Stabilized to prevent peroxide formation, this ether maintains its integrity over extended storage periods, reducing the risk of degradation. The AcroSeal® packaging further enhances stability by minimizing exposure to air and contaminants, preserving purity until use. With a boiling point of 34.6°C and excellent solvency for organic compounds, it serves as a versatile extraction solvent, reaction medium, and eluent in chromatography. Its low viscosity and volatility facilitate rapid evaporation, leaving minimal residue. This grade is particularly suited for applications requiring anhydrous conditions, such as Grignard reactions or lithium-aluminum hydride reductions, where trace water could compromise results. The stabilized formulation meets rigorous quality standards, ensuring consistent performance in analytical and synthetic workflows.
FAQs
1. What is the difference between extra dry and anhydrous diethyl ether?
Extra dry diethyl ether contains trace moisture (typically <0.005%), while anhydrous grades have even lower water content (<0.001%). This product’s extra dry specification balances purity and cost-effectiveness for most lab applications.
2. Can this ether be used with lithium aluminum hydride?
Yes, the 99.5% extra dry grade is compatible with lithium aluminum hydride reactions, though anhydrous grades are often preferred for maximum reactivity. Always verify moisture levels before use in highly sensitive reductions.
3. How should stabilized diethyl ether be stored to prevent peroxide formation?
Store in a cool, dark place away from ignition sources. The AcroSeal® packaging reduces air exposure, but test for peroxides periodically if stored beyond 12 months. Avoid opening near flames or sparks.
4. Is this ether suitable for HPLC or GC analysis?
While it can be used as a solvent in chromatography, HPLC/GC applications typically require specialized grades with lower UV absorbance or residue specifications. Check compatibility with your specific analytical method.
5. What alternatives exist for moisture-sensitive extractions?
For ultra-low moisture requirements, consider anhydrous diethyl ether or tert-butyl methyl ether (TBME). TBME offers lower peroxide risk but different solubility profiles. Always match the solvent to your solute’s properties.
