Description and Uses
DMI, a high purity aprotic solvent, is composed of nitrogen containing five membered ring compound and widely recognized as an epoch making solvent. It is a colorless, transparent, high polar solvent with high thermal and chemical stability and non-corrosiveness. The material has a high boiling point of 222° C, a high flash point of 120° C (open method) / 95° C (close method), and a low melting point of 7.5° C.
1,3-Dimethyl-2-imidazolidinone may be used:
- As substitute solvent for hexamethylphosphoric triamide (HMPA) in the synthesis of 1,2-bis(trimethylsilyl)benzene.
- As solvent during the α-regioselective prenylation of imine.
- As component of mobile phase for the size-exclusion chromatographic analysis of cellulose.
