Application
1-Methylpyrrolidine is extensively used in the synthesis of pyrrolidine based ionic liquids. Some of the other reported applications include:
- Synthesis of ionic liquid electrolytes for primary Li/CFx batteries.
- Preparation of ionic liquid as a reaction medium to carry out sulfuric acid-catalyzed conversion of alkynes to ketones.
- MCM-47, a highly crystalline ferrierite layered silicate, can be synthesized using a diquaternary ammonium salt prepared from the reaction of 1-methylpyrrolidine with 1,4-dibromobutane.

This paper describes a sweeping-micellar electrokinetic chromatography (sweeping-MEKC) technique for the determination of seven benzodiazepines, using, as sweeping carriers, the ionic liquid-type cationic surfactants 1-cetyl-3-methylimidazolium bromide (C(16)MIMBr) and N-cetyl-N-methylpyrrolidinium bromide (C(16)MPYB). These surfactants resemble the commonly employed cationic surfactant cetyltrimethylammonium
