Ethylene Glycol Ethyl Ether CAS#110-80-5
2-Ethoxyethanol is a stable, colorless, flammable liquid that is produced synthetically worldwide. It belongs to the glycol ether solvent family and is commercially known as Ethyl Cellosolve or Cellosolve, a trademark registered by Union Carbide in 1924.
This compound was originally developed to combine the chemical properties of both alcohols and ethers, providing both hydrophilic and lipophilic characteristics while maintaining lower volatility, which contributes to improved production performance. Glycol ethers are synthesized through the reaction of anhydrous alcohols with ethylene oxide.
