Application【应用】
1-Methyl-2-pyrrolidinone may be used as:
  • An alternative eluent to THF in the size exclusion chromatography (SEC) based resolution of coal-derived liquids.
  • Reaction medium to prepare 2-aryl and 2-alkyl benzothiazoles.
  • A solvent in the ultrasonic preparation of metal organic framework (MOF-177) crystals.
It may be used to synthesize single-phase chalcopyrite CuInSe2 nanocrystals and potassium 3-methyl-2-oxo-pyrrolidinenitronate.
