N-Ethyl Pyrrolidone CAS 2687-91-4

N-Ethyl-2-pyrrolidone (NEP, CAS 2687-91-4) is a colorless and transparent strongly polar organic solvent with high chemical stability, weak alkalinity, and low vapor pressure. It can mix freely with water and most organic solvents, and is widely used in oil refining, electronic industry cleaning, and the synthesis of fine chemicals such as pesticides and dyes due to its outstanding solubility and low toxicity.
