1,3-Dimethyl-2-imidazolidinone (DMI) is a cyclic urea used as a high-boiling polar aprotic solvent. It is colourless, transparent, highly polar and has high thermal and chemical stability. It is a homolog of the related solvent DMPU. In many applications, DMI (as well as DMPU) can be used as a substitute or replacement for the carcinogenic solvent HMPA.
DMI has a boiling point of 225 °C, a flash point of 120 °C and a melting point of 8.2 °C. DMI has excellent solvating ability for both inorganic and organic compounds.
DMI is used in a variety of applications including detergents, dyestuffs, electronic materials and in the manufacture of polymers.
DMI is toxic in contact with skin.
