Product Name – 1-Methyl-2-pyrrolidinone, 99.5%, Extra Dry, AcroSeal® Quantity/Pack Size – 100ML, 1LT, 2.5LT Form – Liquid Grade – Extra Dry, 99.5% Application – Solvent for organic synthesis, polymerization, and pharmaceutical intermediates

Product Overview

1-Methyl-2-pyrrolidinone (NMP), 99.5% Extra Dry, is a high-purity, polar aprotic solvent packaged in AcroSeal® bottles to ensure minimal moisture exposure and extended shelf life. This grade is meticulously distilled and treated to achieve ultra-low water content (<50 ppm), making it indispensable for moisture-sensitive reactions such as lithium-ion battery manufacturing, peptide synthesis, and advanced polymer processing. The Extra Dry designation guarantees consistency in critical applications where trace water can compromise yields or product integrity. Its high boiling point (202°C) and miscibility with most organic solvents further enhance its versatility in extraction, purification, and formulation workflows. The AcroSeal® packaging features a tamper-evident cap and inert atmosphere to prevent oxidative degradation, ensuring the solvent remains stable from first to last use. This product adheres to strict quality controls, with batch-specific certificates of analysis verifying its purity, residual moisture, and absence of metallic impurities. Whether used as a reaction medium, cleaning agent, or process solvent, this NMP variant delivers reproducible results in demanding laboratory and pilot-scale environments.

FAQs

1. What is the difference between Extra Dry and standard-grade NMP?

The Extra Dry grade undergoes additional drying processes to reduce water content below 50 ppm, whereas standard grades typically contain 100-500 ppm. This makes Extra Dry ideal for moisture-sensitive chemistry like Grignard reactions or lithium battery electrolyte preparation.

2. Can this NMP be used for HPLC or GC analysis?

While it meets high purity standards, it is not specifically certified as HPLC or GC grade. For chromatographic applications, we recommend solvents labeled explicitly for those techniques to avoid baseline noise or column contamination.

3. How should I store opened bottles of this solvent?

Store opened bottles under nitrogen or argon in a tightly sealed container, away from direct light and heat sources. The AcroSeal® cap should be resealed immediately after use to minimize air exposure.

4. Is this NMP compatible with PTFE or glass labware?

Yes, it is fully compatible with PTFE, glass, and most stainless-steel equipment. However, avoid prolonged contact with some plastics like polystyrene or polycarbonate, as it may cause swelling or degradation.

5. What alternatives exist if I need a lower-boiling solvent with similar polarity?

For applications requiring a lower boiling point, consider dimethylformamide (DMF, bp 153°C) or dimethylacetamide (DMAc, bp 166°C). Both offer comparable polarity but evaporate faster, which may be advantageous for workup procedures.
