[{"from": "human", "value": "Describe this molecule. [C][Branch1][N][C][O][C][C][O][C][C][O][C][C][O][O]"}, {"from": "gpt", "value": "The molecule is an industrial solvent/chemical with a higher boiling point and lower volatility than the lower ethylene glycols. It is especially useful in polyester resins and as a plasticizer. Tetraethylene glycol is also used as a chemical intermediate and as a solvent in the production of inks and dyes. Tetraethylene glycol is often used as a process solvent in hydrocarbon purification processes and as a coupling agent in the production of textile lubricants and formulations."}]
