Description

CAS: 80-73-9 | C5H10N2O | 114.15 g/mol

1,3-Dimethyl-2-imidazolidinone is used as a high-boiling polar aprotic solvent. It is used as a substitute solvent for toxic hexamethylphosphoramide. It finds application in detergents, dyestuffs, electronic materials and in the manufacture of polymers. It is involved in the preparation of 1,2-bis(trimethylsilyl)benzene. Further, it is utilized as a solvent during alfa-regioselective prenylation of imines. In addition to this, it constitutes the mobile phase during size-exclusion chromatographic analysis of cellulose.
