| Uses | 1-Methyl-2-pyrrolidone is a polar solvent that is used in organic chemistry and polymer chemistry. Large scale applications include the recovery and purification of acetylenes, olefins, and diolefins, gas purification, and aromatics extraction from feedstocks. 1-Methyl-2-pyrrolidinone is a versatile industrial solvent. NMP is currently approved for use only in veterinary pharmaceuticals. The determination of the disposition and metabolism of NMP in the rat will contribute toward understanding the toxicology of this exogenous chemical which man may likely be exposed to in increasing amounts. |
| Uses | Solvent for high-temperature resins; petrochemical processing, in the microelectronics fabrication industry, dyes and pigments, industrial and domestic cleaning compounds; agricultural and pharmaceutical formulations |
