N-Ethyl-2-Pyrrolidone, NEP

Pyrrolidone and its derivatives are used as Intermediates for the synthesis of agrochemicals, pharmaceuticals, textile auxiliaries, plasticizers, polymer solvent, stabilizers, specialty inks and as a nylon precursor.

N-Ethyl-2-Pyrrolidone is a keto-pyrrole, that is a 5-membered lactam structure compound (gamma-butyrolactam). Lactam structure compound including pyrrolidone has good solvency property, therefore Pyrrolidone is useful in industrial application.

In the field of medicine, N-Ethyl-2-Pyrrolidone is an important part of antibiotics, such as penicillin. These structures, cyclic esters and analogues, are active nucleuses in pharmacological activity and flavorings.

In industry, Lactams have big demand in artificial fibre industry. They are polymerizable and used as nylon precursors.

N-Ethyl-2-Pyrrolidone (NEP) is used as a solvent for surface treatment for textiles, metal coated plastics, polymers, and paint removing.
