Description

Triethylene glycol dimethyl ether ( CAS 112-49-2 ), commercially known as Triglyme, is a high-boiling, aprotic ether solvent used across demanding industrial and specialty chemical applications. Its low volatility and chemical stability make it a preferred carrier and reaction medium where conventional solvents fall short. In pharmaceutical manufacturing, it functions as a reaction solvent. This solvent is ideal for sensitive synthesis steps requiring a stable, non-protic environment with a high boiling point. The electronics industry relies on it as a solvent in electrolyte formulations. In lithium batteries, its coordination chemistry with lithium ions directly influences cell performance. In oil and gas processing, it is used as an extraction and absorption solvent for gas treatment. Metalworking and lubricant formulators incorporate it as a carrier fluid in specialty formulations requiring thermal stability. It remains effective even under elevated operating conditions. Triglyme is supplied as a clear liquid in standard packaging ranging from drums to IBC containers and bulk quantities. Technical grade is the most common commercial specification available. High-purity grades are available to meet the tighter requirements of battery electrolyte and pharmaceutical synthesis applications. Buyers should confirm purity levels and water content specifications. Sourcing for electrochemical or synthesis-critical end uses requires careful attention to technical data sheets. This ensures the material meets the necessary performance benchmarks for your process. Contact us for supply of Triethylene glycol dimethyl ether Request Quote
