N-Vinyl-2-pyrrolidone, commonly known as NVP or Vinylpyrrolidone, is a reactive vinyl monomer with CAS number 88-12-0. Its molecular formula is C6H9NO, with a molecular weight of 111.14 g/mol. Our industrial and pharmaceutical grade product appears as a clear, colorless liquid without visible impurities, with strict control over purity, residual monomers, moisture and chromaticity.

As the primary raw material for the synthesis of polyvinylpyrrolidone (PVP), NVP is widely used in various industries. It undergoes free radical polymerization to form PVP, a versatile polymer with excellent solubility, biocompatibility and film-forming properties. NVP is also extensively used as a pharmaceutical intermediate, cosmetic raw material, adhesive monomer and reactive diluent in coatings. Its unique combination of reactivity and biocompatibility makes it an essential raw material in many high-end applications.

Our N-vinyl-2-pyrrolidone is produced with advanced synthesis and purification technology, with full batch traceability and complete supporting quality documents. It contains a small amount of stabilizer to prevent self-polymerization during storage and transportation. We can provide customized specifications to meet specific customer requirements and ensure long-term stable bulk supply for global industrial manufacturers.

A1: Yes, our NVP contains a small amount of stabilizer (typically 50-200 ppm of MEHQ or hydroquinone) to prevent self-polymerization during storage and transportation. The stabilizer content is strictly controlled and does not affect most polymerization processes. For applications requiring stabilizer-free NVP, please contact us for customized products.

A2: NVP has a shelf life of 12 months when stored in tightly sealed original containers under nitrogen atmosphere at temperatures between 5-25℃. It should be stored away from heat sources, direct sunlight and strong oxidizing agents. Containers should be kept tightly closed when not in use to prevent air exposure and moisture absorption.

A3: NVP is a reactive monomer that can undergo self-polymerization if exposed to heat, light or initiators. Polymerized NVP forms a viscous gel or solid that is insoluble in most solvents. Once polymerized, the product cannot be used and must be disposed of properly.

A4: NVP is a toxic substance and may cause skin and eye irritation. Required PPE includes:

• Chemical-resistant gloves (nitrile or butyl rubber)
• Safety goggles with face shield
• Chemical-resistant apron and protective clothing
• Respiratory protection if working in poorly ventilated areas

A5: NVP itself is not approved for direct food contact. However, polymers derived from NVP (such as PVP) are approved for use in food contact applications in most countries when used in accordance with relevant regulations.

A6: Pharmaceutical grade NVP has stricter control over impurities, especially residual 2-pyrrolidone, heavy metals and microbial content. It also meets additional regulatory requirements for pharmaceutical applications. Industrial grade NVP is suitable for most general industrial applications such as polymer synthesis, adhesives and coatings.
