2-pyrrolidone

2-Pyrrolidone (CAS 616-45-5) is a cyclic lactam used across industrial and specialty chemical markets as a solvent, monomer, and functional additive. It serves as a direct precursor to polyvinylpyrrolidone and as an intermediate in the synthesis of other N-substituted pyrrolidones.

Buyers source it primarily for polymer production, ink formulation, and personal care applications. In inkjet and printing ink systems, it functions as a co-solvent and humectant that controls drying rate and prevents nozzle clogging in aqueous formulations.

It acts as a key monomer and building block in the manufacture of PVP and related polymers used in pharmaceutical binders, adhesives, and coatings. Personal care formulators incorporate it as a humectant and penetration enhancer in skin and hair care products.

In electronics manufacturing, it is used as a processing solvent for polymer films and specialty coatings where low residue and compatibility with sensitive substrates matter. This versatility makes it a staple in high-performance chemical manufacturing.

2-Pyrrolidone is supplied as a colorless to pale yellow liquid in drum and IBC quantities. Technical grade and high-purity grades are the standard commercial offerings, with pharmaceutical-grade material available to meet USP and Ph. Eur. specifications.

Packaging options typically range from small containers for specialty applications to bulk tanker supply for polymer production. Reliable logistics ensure that the product maintains its chemical integrity during transport and storage for industrial use.
