Popis

Application

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.
