  • Applications

    1,3-Dimethyl-2-imidazolidinone (CAS 80-73-9) is a high-boiling polar aprotic solvent used primarily as a processing solvent for polymers and resins, including cellulose derivatives, in synthesis and formulation. It is also employed as a solvent medium for coatings, inks, and adhesives formulations, aiding dissolution of resins and additives. Its stability and polarity make it suitable as a solvent component in lithium-ion battery electrolytes and other electrochemical systems. It may be used as a processing solvent or co-solvent in pharmaceutical manufacturing and formulation development, and is occasionally evaluated for electronic/industrial material processing applications where high-temperature, polar solvents are preferred.
