Product Overview
Product Overview
N-Ethyl-2-pyrrolidone (NEP, CAS 2687-91-4) is a high-boiling polar aprotic solvent with the molecular formula C6H11NO and a molecular weight of 113.16. It is typically supplied as a clear, colorless liquid and provides strong solvency for a broad range of resins, polymers, and organic materials. Its low volatility and broad liquid range support applications in coatings, electronic chemicals, polymer processing, industrial cleaning, and fine-chemical formulations.
Key Applications
- Coatings and Resins: Solvent for resin dissolution, coating formulation, flow control, and processing.
- Electronic Chemicals: Used in electronic-material, cleaning, and stripping formulations where the applicable electronic-grade specification is met.
- Polymer Processing: Applied in polymer dissolution, membrane preparation, fiber processing, and specialty-material formulations.
- Industrial Cleaning: Used in professional systems for removing oils, resins, polymer residues, and difficult organic soils.
- Fine Chemicals: Reaction medium, extraction solvent, or formulation solvent for organic synthesis and process development.
Product Features
- Clearly identified by CAS 2687-91-4
- High-boiling polar aprotic solvent with broad solvency for resins and organic materials
- Low vapor pressure and broad liquid range for controlled-evaporation processes
- Industrial and tighter-control grades may be available subject to the batch COA
- NEP carries health-hazard classifications; engineering controls and personal protection must follow the SDS, local regulations, and occupational-exposure requirements
Product Advantages
- Strong solvency for a broad range of resins, polymers, and organic materials
- High boiling point and low volatility support controlled process evaporation
- Applicable to coatings, electronic chemicals, polymer processing, and industrial cleaning formulations
- Purity, moisture, color, and impurities managed through batch-specific COA requirements
