Description

n-Methyl-2-Pyrrolidone (NMP) is a powerful, high-boiling, dipolar 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 chemical is essential for industries requiring precision cleaning, polymer synthesis, and surface coating formulations.

Application

• Electronics Manufacturing: Primary solvent for photoresist stripping and precision cleaning of semiconductor wafers and LCD panels.
• Polymer & Petrochemical Processing: Selective extraction solvent for the purification of aromatics (e.g., BTX) and butadiene, and as a reaction medium for polyimide, PEEK, and other high-performance polymer synthesis.
• Industrial & Metal Surface Cleaning: Key component in paint strippers, degreasers, and formulations for cleaning metal parts and machinery due to its powerful solvency.
• Pharmaceutical & Agrochemical Synthesis: High-purity solvent for API synthesis, crystallization, and as a reaction medium in pesticide formulation.
• Lithium-Ion Battery Production: Used as a processing solvent in the coating of electrode slurries for lithium-ion batteries.
• Chemical Intermediates: Serves as a precursor in the synthesis of pharmaceuticals, pesticides, and other specialty chemicals.

Quality Control

Our n-Methyl-2-Pyrrolidone is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications for industrial and electronic grades. Certificates of Analysis (COA) are provided with each shipment to guarantee traceability and batch-to-batch consistency.

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 such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C. The container should be kept tightly sealed when not in use to minimize moisture absorption.
