For procurement managers and R&D scientists in the chemical industry, understanding the precise specifications of materials like 2-Pyrrolidone (CAS 616-45-5) is crucial for ensuring product quality and manufacturing efficiency. As a potent polar solvent, the performance of 2-pyrrolidone is directly linked to its purity and physical characteristics. When you are ready to buy 2-pyrrolidone, paying close attention to these details will lead to successful sourcing from a trusted 2-pyrrolidone supplier.

The primary specification to consider is purity. Industrial-grade 2-pyrrolidone typically requires a minimum purity of 99.9%. This high level of purity is essential for applications where contaminants could negatively affect reaction yields, product stability, or final product appearance, particularly in pharmaceutical and fine chemical synthesis. A reliable 2-pyrrolidone manufacturer will provide a Certificate of Analysis (COA) detailing the exact purity and other critical parameters.

Other important specifications for 2-pyrrolidone include:

  • Color: Usually specified as a maximum value (e.g., ≤20 GBL) to ensure clarity, important for inks and clear coatings.
  • GBL (Gamma-Butyrolactone) content: A low residual GBL content (e.g., ≤0.05%) is indicative of a well-purified product.
  • Water content: Typically limited to a maximum percentage (e.g., ≤0.10%) to maintain solvent integrity and prevent unwanted side reactions.
  • Refractive Index and Density: These physical properties serve as additional checks for product identity and quality.
