1. Name: 1-Ethyl-2-Pyrrolidone, NEP, N-Ethylpyrrolidone

2. Fomula: C₆H₁₁NO

3. CAS NO.: 2687-91-4

4. Discription:
N-ethylpyrrolidone (NEP) is the lactam of 4-ethylaminobutyric acid and a very weak base. NEP is a chemically stable and powerful polar solvent. These characteristics are highly useful in a variety of chemical reactions where an inert medium is of concern. Despite the stability of NEP, it can also play an active role in certain reactions: Hydrolysis, oxidation, condensation, conversion with chlorinating agents, polymerization and o-alkylation, and related reactions.
