Product Overview
1-Methyl-2-Pyrrolidone (NMP) LR is a high-purity, polar aprotic solvent widely used in laboratory settings due to its exceptional solvency power and thermal stability. This LR-grade NMP is meticulously refined to ensure minimal impurities, making it ideal for critical applications requiring consistent performance. Its low volatility and high boiling point (202°C) allow for prolonged use without significant evaporation, while its miscibility with water and organic solvents enhances versatility. The solvent’s ability to dissolve a broad range of polar and nonpolar compounds—including resins, polymers, and inorganic salts—makes it a staple in synthesis, extraction, and purification processes. Its hygroscopic nature necessitates proper storage to maintain purity, and its mild odor ensures a tolerable working environment. Compatible with most lab-grade glassware and stainless steel, NMP LR is a reliable choice for processes demanding precision and reproducibility. Always handle with standard lab safety protocols, as it may cause mild skin irritation upon prolonged exposure.
