Descriptions:
pubchem: Pyrrolidin-2-one is the simplest member of the class of pyrrolidin-2-ones, consisting of pyrrolidine in which the hydrogens at position 2 are replaced by an oxo group. The lactam arising by the formal intramolecular condensation of the amino and carboxy groups of gamma-aminobutyric acid (GABA). It has a role as a metabolite and a polar solvent.
chebi: The simplest member of the class of pyrrolidin-2-ones, consisting of pyrrolidine in which the hydrogens at position 2 are replaced by an oxo group. The lactam arising by the formal intramolecular condensation of the amino and carboxy groups of γ-aminobutyric acid (GABA).
chembl: 2-PYRROLIDONE is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: 2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam.  It is a colorless liquid that is miscible with water and most common organic solvents.
2-Pyrrolidone itself and it various derivatives, especially N-methylpyrrolidone, have a variety of industrial uses.
