2-Pyrrolidinone (2-Pyrrolidone, 2-P) is an important polar aprotic solvent and chemical intermediate. It is widely used in pharmaceutical synthesis, polymer production, electronics manufacturing, coatings, inks, adhesives, and agrochemical formulations. It serves as a precursor for N-vinyl-2-pyrrolidone (NVP), which is used to manufacture polyvinylpyrrolidone (PVP). It is also applied as a solvent for resins, dyes, polymers, and high-performance materials.
