1,3 Dimethyl-2-Imidazolidinone (DMI)
CAS Number: 80-73-9
Description
1,3 Dimethyl-2-Imidazolidinone (DMI) is a high-boiling, dipolar aprotic solvent widely recognized for its outstanding solvency power, thermal stability, and chemical inertness. It belongs to the imidazolidinone family and is valued in processes requiring strong solubilizing capacity, especially for polymers, resins, pharmaceuticals, agrochemicals, and electronics applications.
Its unique structure enables it to dissolve both polar and non-polar compounds, making it highly versatile in specialty chemical formulations. Compared to conventional solvents like NMP or DMF, DMI offers lower toxicity, high flash point, and superior safety profile, making it a preferred choice in industries striving for sustainable operations.
