General description
Tetraethylene glycol dimethyl ether or tetraglyme is an organic aprotic colourless solvent with film forming ability.

Application
Tetraglyme coating was applied on glucose sensors, such as Nafion by RF to render it “non fouling” and enhancing linking of bio mimetic molecules to the surface. Tetraglyme helps in selective adsorption of proteins while promoting cell adhesion.[1] Other general uses include as an electrolyte in lithium ion batteries.

Tetraethylene glycol dimethyl ether is an inert solvent especially well suited for API synthesis.

Tetraglyme
CAS: 143-24-8

Tetraglyme, also called tetraethylene glycol dimethyl ether, is a polar aprotic solvent with excellent thermal and chemical stability. Glymes, or glycol ethers, are a widely used family of saturated polyethers for increasing anion reactivity in a given system, thus affecting selectivity and reaction rates. Tetraglyme is one of the heavier ethylene oxide based glymes available commercially.

Tetraethylene glycol dimethyl ether is an ideal solvent for separation processes and high temperature reactions. It is used as an additive for adsorption refrigeration and heat pumps (HVAC systems), as a reagent for lithium-ion batteries, and as a solvent for paints, cleaning products, inks, adhesives, and other coatings. It is a strong emulsifier, and can help prevent clogging of ink printer heads.

This compound is an environmentally-friendly alternative to many lab solvents, so it is also useful as an inert solvent for API synthesis in the pharmaceutical industry.

Bis(2-(2-methoxyethoxy)ethyl)ether, also named tetraethylene glycol dimethyl ether (TEGDME) or tetraglyme (used herein) is an organic, colourless aprotic solvent with high chemical and thermal stability. It is used in e.g. paints and coatings as well as in
separation processes and high temperature reactions.

Tetraglyme (tetraethylene glycol dimethyl ether) is an effective solvent for paints and coatings. It has high solvency and dispersants for pigments and dyes and can be used effectively in water-based coatings.

Based on data for tetraglyme and data read across from source substances monoglyme, diglyme and triglyme, further supported by assumed common metabolites 2-methoxyethanol and methoxyacetic acid.

Tetraethylene Glycol Dimethyl Ether is listed as a Substance of Very High Concern under reach regulations. The glow discharge plasma deposition (GDPD) of Tetraethylene Glycol Dimethyl Ether is introduced as a novel method for obtaining surfaces that are resistant to protein adsorption and cellular attachment. Analysis of films by x‐ray photoelectron spectroscopy and several biological assays indicate the formation of a fouling resistant, PEO‐like surface on several substrata (e.g., glass, polytetrafluoroethylene, polyethylene). Adsorption of 125I‐radiolabelled proteins (fibrinogen, albumin and IgG) from buffer and plasma was very low (typically <20 ng/cm2) when compared to the untreated substrata, which exhibited much higher levels of protein adsorption.
