2-pyrrolidone

2-Pyrrolidone (CAS 616-45-5) is a cyclic lactam used as a solvent, monomer, and functional additive.

Where is 2-pyrrolidone used?

• Polymer production: direct precursor to polyvinylpyrrolidone and intermediate in the synthesis of other N-substituted pyrrolidones
• Inks: co-solvent and humectant that controls drying rate and prevents nozzle clogging in aqueous inkjet and printing ink systems
• Pharmaceutical binders, adhesives, and coatings: monomer and building block in the manufacture of PVP and related polymers
• Personal care: humectant and penetration enhancer in skin and hair care products
• Electronics manufacturing: processing solvent for polymer films and specialty coatings where low residue and compatibility with sensitive substrates matter

Good to know: Technical grade and high-purity grades are the standard commercial offerings, with pharmaceutical-grade material available to meet USP and Ph. Eur. specifications.
