Product Overview
Ethylene glycol dimethyl ether (monoglyme) is a high-purity, anhydrous solvent designed for demanding laboratory applications. With a minimum assay of 99% and extra dry formulation, it ensures minimal water content (<50 ppm), making it ideal for moisture-sensitive reactions. The AcroSeal® packaging provides an inert atmosphere, preserving purity and extending shelf life. This solvent exhibits excellent solvating power for polar and nonpolar compounds, with a low viscosity (0.46 cP at 25°C) and moderate boiling point (85°C). Its aprotic nature and dielectric constant of 7.2 enable efficient dissolution of inorganic salts and organic intermediates. The low surface tension (21.7 mN/m) enhances wetting properties, while the flash point of 1°C requires careful handling. Compatible with most glassware and PTFE-sealed containers, it serves as a versatile alternative to THF or dioxane in organometallic chemistry. Store under nitrogen in a cool, ventilated area away from ignition sources.
FAQs
1. What is the typical moisture content in this extra dry grade?
The extra dry grade contains less than 50 ppm water content, verified by Karl Fischer titration.
2. Can this be used as a direct replacement for THF in Grignard reactions?
Yes, but reaction rates may vary due to its higher dielectric constant compared to THF.
3. What materials are incompatible with this solvent?
Avoid contact with strong oxidizing agents, alkali metals, and some plastics like polyethylene.
4. How should I dispose of waste containing this solvent?
Collect in approved solvent waste containers and dispose through licensed hazardous waste handlers.
5. Does the AcroSeal® packaging require special opening procedures?
Use the built-in septum port with a syringe or vent carefully to avoid pressure buildup.
