# Analysis and dosage of N-Methyl-2 Pyrrolodone (NMP) – (CAS No. 872-50-4)

## You wish to carry out an analysis of N-Methyl-2-Pyrrolidone (NMP)

### What is N-Methyl-2-Pyrrolidone (NMP)?

**N-Methyl-2-Pyrrolidone (NMP)**, **CAS 872-50-4**, is a polar organic solvent of the lactam family. Widely used in industry for its solubility properties, it is used in:

- **Polymer manufacturing** (coatings, resins, engineering plastics)
- **Lithium-ion batteries** (cathodes, electrolytes)
- **Pharmaceuticals** and medical devices
- **Surface coatings, inks, and paints**
- **Petrochemical and electronic processing**

However, NMP is classified as a **reproductive toxicant (CMR – category 1B)**, and its use is strictly regulated by the **REACH** regulation.

## FAQ

 What are the risks associated with N-Methyl-2-Pyrrolidone (NMP)?
NMP is classified as a reproductive toxicant (CMR – category 1B). It can cause damage to fertility and development. Its use is therefore strictly regulated, particularly in Europe by REACH.

 What are the regulatory restrictions regarding NMP?
Since 2020, NMP has been subject to the REACH restriction (entry no. 71 of Annex XVII)

 How to detect and quantify NMP in a product?
The most common methods are:

- Gas chromatography-mass spectrometry (GC-MS) for complex matrices.
- HPLC for liquid formulations.
- Spectroscopic analysis (FTIR, NMR) to confirm the presence of the molecule.

 In which products is NMP found?
NMP is used in:

- Lithium-ion batteries (electrode manufacturing)
- Coatings, paints, and inks
- Pharmaceuticals (synthesis and formulation)
- Electronics and microtechnology
- Petrochemicals
