Product Name – Tetraethylene glycol dimethyl ether, 98+% Quantity/Pack Size – 1kg, 250g Form – Liquid Grade – 98%+ (Synthesis Grade) Application – Solvent, reaction medium, extraction agent
Product Overview
Tetraethylene glycol dimethyl ether (98%+) is a high-purity, low-volatility solvent widely used in organic synthesis and chemical processing. This colorless, hygroscopic liquid features a high boiling point (275°C), making it ideal for reactions requiring elevated temperatures without premature evaporation. Its polar aprotic nature enables excellent solvation of both polar and nonpolar compounds, enhancing reaction efficiency. The ether’s stability under basic and neutral conditions ensures consistent performance in sensitive applications. With minimal water content (<0.1%) and negligible impurities, this grade meets stringent laboratory requirements for reproducibility. The compound’s low toxicity profile and compatibility with most glassware and metals further simplify handling. Its miscibility with common organic solvents like alcohols, ketones, and hydrocarbons allows for versatile formulation adjustments. The 98%+ purity level guarantees minimal byproduct formation, reducing purification steps in downstream processes.
FAQs
1. Is this tetraethylene glycol dimethyl ether compatible with lithium aluminum hydride?
It can be used with lithium aluminum hydride, but pre-drying is recommended to avoid side reactions with residual moisture.
2. What’s the shelf life of this chemical when stored properly?
When kept in a tightly sealed container under inert gas at room temperature, the shelf life is 24 months from the date of manufacture.
3. Can this replace diglyme in certain reactions?
Yes, it can substitute diglyme where higher boiling points or increased chain length are advantageous, though reaction kinetics may vary.
4. Does this product contain any stabilizers or inhibitors?
No stabilizers or inhibitors are added; the 98%+ purity refers to the base compound without additives.
5. What’s the recommended storage temperature range?
Store between 15°C to 25°C in a well-ventilated area, away from oxidizing agents and direct sunlight.
