Triethylene glycol CAS 112-27-6

Triethylene glycol is a colorless, odorless, hygroscopic, viscous liquid that is soluble in water and ethanol and has stable properties. It has hydrophilic groups in its structure, which can improve its water solubility. It is an important monomer for synthesizing photosensitive resins and crosslinking agents, and is also used in adhesives for polyester film bases. It should be stored in a cool, dry place.
