Product Overview
Bis(2-methoxyethyl) ether, also known as diglyme, is a high-purity solvent offered in Extra Dry grade (99%+ purity) with AcroSeal® packaging to ensure minimal moisture contamination. This ether is widely valued for its excellent solvating properties and low water content, making it ideal for applications requiring anhydrous conditions. The Extra Dry designation guarantees rigorous drying processes, reducing water content to trace levels, which is critical for reactions sensitive to moisture. Its low viscosity and high boiling point provide stability across a range of temperatures, while the AcroSeal® technology preserves purity by preventing atmospheric moisture ingress during storage. The solvent’s chemical structure, featuring two methoxyethyl groups, enhances its ability to dissolve polar and nonpolar compounds, making it versatile for complex synthesis. Compatible with most laboratory glassware and metal equipment, it is a reliable choice for demanding protocols where consistency and reproducibility are paramount.
FAQs
1. What is the difference between Extra Dry and standard-grade bis(2-methoxyethyl) ether?
The Extra Dry grade undergoes additional drying processes to reduce water content to less than 50 ppm, whereas standard grades may contain higher moisture levels, making them less suitable for moisture-sensitive reactions.
2. Can this solvent be used with lithium aluminum hydride (LiAlH4) reactions?
Yes, the Extra Dry grade’s low water content makes it compatible with highly reactive reducing agents like LiAlH4, where trace moisture could compromise reaction outcomes.
3. How should I store bis(2-methoxyethyl) ether to maintain its purity?
Store the sealed AcroSeal® bottle in a cool, dry place away from direct sunlight and heat sources. Once opened, use under inert gas (e.g., nitrogen) to minimize moisture absorption.
4. Is this solvent compatible with plastic labware?
While it is generally safe with most lab plastics like PTFE or HDPE, prolonged contact may cause swelling or degradation in some polymers. Always verify compatibility with your specific labware material.
5. What alternatives exist if bis(2-methoxyethyl) ether is unavailable?
Alternatives include other glycol ethers like diethylene glycol dimethyl ether (diglyme) or tetraethylene glycol dimethyl ether (tetraglyme), though their boiling points and solvating properties may differ.
