Application

N-Methylpyrrolidine can be used as a starting material to synthesize:
N-methyl pyrrolidine-zinc borohydride (ZBHNMP), a reducing agent for reduction of aldehydes, ketones, acid chlorides, and esters. ZBHNMP is also used in the reductive amination of aldehydes and ketones to their corresponding amines.
N-alkyl-N-methyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide ionic liquids.
N-methylpyrrolidine-2-one hydrotribromide applicable as a catalyst for aziridination of alkenes.

Ionic liquids and plastic crystals based on pyrrolidinium cations are recognised for their advantageous properties such as high conductivity, low viscosity, and good electrochemical and thermal stability. The pyrrolidinium ring can be substituted with symmetric or asymmetric alkyl chain substituents
