Product Overview

1-Methyl-2-pyrrolidone (NMP) GC is a high-purity, polar aprotic solvent renowned for its exceptional solvating power and thermal stability. This GC-grade variant is meticulously purified to ensure minimal impurities, making it ideal for sensitive analytical applications where consistency and reliability are critical. With a boiling point of 202°C and excellent miscibility with water and organic solvents, NMP serves as a versatile medium for dissolution, extraction, and reaction processes. Its low volatility and high flash point enhance safety during prolonged use in laboratory settings. The solvent’s unique dipole moment and hydrogen-bonding capacity enable efficient interaction with a wide range of polar and nonpolar compounds, ensuring optimal performance in chromatographic separations and synthetic protocols. Packaged in airtight, chemically resistant containers, this NMP variant maintains its integrity during storage and handling, reducing the risk of contamination or degradation over time.

FAQs

1. What is the typical shelf life of NMP GC when stored properly?

When stored in a tightly sealed container at room temperature, away from direct sunlight and moisture, NMP GC retains its specified purity for up to 24 months from the date of manufacture. Always check the label for the exact expiration date.

2. Is this NMP grade compatible with HPLC or only GC applications?

While this variant is labeled as GC grade due to its high purity, it can also be used in HPLC applications where ultra-low impurity levels are required. However, for dedicated HPLC use, verify compatibility with your specific column and mobile phase requirements.

3. Can NMP GC be used as a substitute for DMSO in certain reactions?

NMP and DMSO share some solvating properties, but they are not always interchangeable. NMP is often preferred for reactions requiring higher thermal stability or where DMSO’s sulfur content may interfere. Test compatibility in small-scale trials before full substitution.

4. What precautions should be taken when handling NMP GC?

NMP is a mild skin and eye irritant. Always wear nitrile gloves, safety goggles, and a lab coat when handling. Work in a well-ventilated area or under a fume hood to avoid inhalation, and avoid prolonged or repeated skin contact.

5. Does this product contain any stabilizers or additives?

This GC-grade NMP is supplied without added stabilizers or preservatives to maintain its purity. The absence of additives makes it suitable for applications where even trace contaminants could affect results.
