2-Pyrrolidone (2-P)
pyrrolidin-2-one
CAS# 616-45-5
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.
Uses of 2-Pyrrolidone
2-Pyrrolidone serves as an effective polar solvent in diverse industries. In petrochemical extraction, it aids in separating aromatics and purifying hydrocarbons. For polymer production, it’s essential in manufacturing membranes, synthetic resins, and polyols. In the coatings and inks sector, it acts as a dispersing agent for pigments, dyes, and printing inks, enhancing solubility and stability. Additionally, it’s used in pesticide and insecticide formulations for improved efficacy, as well as in cleaning and stripping applications for electronics and surfaces. Its biocompatibility supports limited pharmaceutical roles as a metabolite intermediate.
