2,4,6,8,10,12-Hexaoxatridecane, commonly known as triethylene glycol dimethyl ether (triglyme), is a polar aprotic solvent utilized in various chemical and industrial applications. It excels at solvating metal cations, making it ideal for organometallic reactions such as those involving Grignard or organolithium reagents. In the energy sector, it serves as a co-solvent in lithium-ion battery electrolytes to improve ionic conductivity and stability. It is also used as a solvent in polymer processing, extractions, and the synthesis of fine and specialty chemicals, including pharmaceuticals, where its ether linkages provide chelating properties and low toxicity.
