DescriptionECHEMI Editorial ReferenceClear colorless liquid or low melting solid 2-Pyrrolidone undergoes the reactions of a typical lactam, e.g. ring opening, attack on the carbonyl group, and replacement of hydrogens alpha to the carbonyl group. Strong acids and bases catalyze the hydrolysis of 2-pyrrolidone to 4-aminobutanoic acid (GABA). The hydrogen atom on the nitrogen atom is easily replaced by alkylation reactions with alkyl halide or sulfates, or reaction with acid anhydrides, acyl halides, ethylene oxide, and styrene. Con
Liquid|Solid|LIGHT YELLOW LIQUID.
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 polar solvent and a metabolite.Basic Info-
