Description

n-Methylpyrrolidone (NMP) is a powerful, high-boiling, polar aprotic solvent with exceptional solvency for a wide range of organic and inorganic materials. Its unique combination of chemical stability, low volatility, and high selectivity makes it a critical processing agent in advanced manufacturing. This versatile compound is essential for industries requiring precision cleaning, efficient polymer processing, and high-purity chemical synthesis, including electronics, pharmaceuticals, and agrochemicals.

Application

• Electronics Manufacturing: Primary solvent for photoresist stripping and cleaning of silicon wafers and LCD panels.
• Polymer & Petrochemical Processing: Key solvent for the extraction and purification of aromatics (e.g., BTX) and as a reaction medium for polyimide, PEEK, and other high-performance polymers.
• Industrial Cleaning & Surface Treatment: Effective degreaser and paint stripper for industrial equipment and coatings removal.
• Pharmaceutical Synthesis: Used as a reaction solvent in the production of active pharmaceutical ingredients (APIs) due to its high purity and solvency power.
• Agrochemical Formulation: Carrier solvent for pesticides and herbicides.
• Lithium-Ion Battery Production: Solvent for electrode slurry preparation in the manufacturing of battery cathodes and anodes.

Quality Control

Our n-Methylpyrrolidone is manufactured under a strict quality management system. Every batch is analyzed to ensure it meets high-purity standards suitable for technical and electronic grade applications. A comprehensive Certificate of Analysis (COA) detailing purity, water content, and key impurity profiles is provided with each shipment to guarantee consistent performance and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic nature, containers should be kept tightly sealed when not in use to prevent moisture absorption. Recommended storage temperature is between 15°C and 25°C.
