It is used to absorbhydrogen sulfidefromsour gasand hydrodesulfurization facilities. Due to its good solvency properties NMP is used to dissolve a wide range ofpolymers. It is also used as a solvent for surface treatment oftextiles, resins, and metal coated plastics or as apaint stripper. It is utilized as a solvent in the commercial preparation ofpolyphenylene sulfide. In the pharmaceutical industry,N-methyl-2-pyrrolidone is used in the formulation for drugs by both oral and transdermal delivery routes. It is also used heavily inlithium ion batteryfabrication, as a solvent for electrode preparation, though there is much effort to replace it with solvents of less environmental concern, like water.Specification:ItemSpecificationContent%99.85minMoisture%0.03maxColorityAPHA10maxFreeAmineppm50maxTotalAmineppm50maxCAS 872-50-4 99.85% Electron Grade N-Methyl Pyrrolidone NMP
