Description

Tetraethylene glycol dimethyl ether (CAS 143-24-8 ), commercially known as Tetraglyme or by the abbreviation TEGDME, is a high-boiling, aprotic ether solvent used across demanding industrial and research-grade applications. Its thermal stability and low volatility make it a preferred solvent where conventional options fail under process conditions. In battery and electrochemical research, TEGDME functions as an electrolyte solvent. It is used for lithium-air and lithium-sulfur systems, where its electrochemical stability directly influences cycle performance. Pharmaceutical and biotech manufacturers use it as a reaction solvent and carrier. It is ideal for sensitive active ingredients requiring an inert, non-protic environment. In polymer processing, it supports polymerization reactions and acts as a cross-linking medium for product consistency. Electronics manufacturers apply it in specialty cleaning and formulation processes where residue-free, high-purity solvent performance is required. TEGDME is supplied as a clear liquid in standard packaging. Standard industrial packaging includes drums and IBC containers. Technical and high-purity grades are available, with high-purity specifications commonly required for battery-grade and pharmaceutical applications. Anhydrous grades are also offered for moisture-sensitive processes in electrochemical and synthesis applications. This ensures optimal performance in environments where water content must be strictly controlled. Contact us for supply of Tetraethylene glycol dimethyl ether Request Quote
