DMI, a new aprotic solvent as an alternative for DMF, DMA or DMSO
 

DMI (1,3 Dimethyl-2-Imidazolidinone, CAS number 80-73-9) is a colorless,
transparent, high polar solvent with high thermal and chemical stability
and non-corrosiveness. It has an excellent solubility for inorganic
and organic compounds and high dielectric constant. More information
about its physicochemical properties, applications and safe handling
can be found at

DMI oxidizes, is there an easy way to fill the head space with N?

"DMI is typically stored in iron, can or drum containers whose net weight is 18 kg and 200 kg respectively. DMI has a hygroscopic property and is oxidized more or less when it is exposed to air for a long period of time. Therefore, its storage containers should be kept sealed with inactive gas such as nitrogen."
