Description

n-Vinyl-2-Pyrrolidone is a versatile, highly reactive monomer featuring a vinyl group attached to the lactam ring of 2-pyrrolidone. This compound matters as a critical building block for synthesizing water-soluble polymers and functional materials with tailored properties. It is essential for manufacturers in the pharmaceutical, personal care, adhesive, and specialty chemical industries seeking to develop advanced polymeric products.

Application

• Pharmaceutical Excipient Synthesis: Key monomer for producing polyvinylpyrrolidone (PVP), a widely used binder, disintegrant, and solubilizing agent in tablet formulations.
• Personal Care & Cosmetics: Used in the manufacture of PVP and copolymers that act as film-formers, hair fixatives, and thickeners in hairsprays, gels, and shampoos.
• Adhesive & Coating Formulations: Serves as a reactive diluent and modifier to enhance adhesion, flexibility, and water solubility in industrial adhesives and specialty coatings.
• Photoresist & Electronics Chemicals: Employed in the synthesis of polymers for photoresist applications in semiconductor manufacturing and printed circuit boards.
• Ion-Exchange Resins & Membranes: A precursor for functional polymers used in water treatment, separation technologies, and fuel cell membranes.
• Biomedical Hydrogels: Utilized in creating cross-linked, biocompatible hydrogel networks for drug delivery systems and wound dressings.
• Chemical Intermediate: Acts as a versatile intermediate for further chemical modifications and the synthesis of other N-vinyl amides and specialty monomers.

Quality Control

Our n-Vinyl-2-Pyrrolidone is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert gas blanket (e.g., nitrogen) and keep containers tightly sealed when not in use. Typical recommended storage temperature is 2-8°C to maximize stability and shelf life.
