Uses

N-Methylsuccinimide is used as a model compound to investigate the mechanism of enolization step by density-functional theory (DFT) calculations. N-Methylsuccinimide is a metabolite of N-methyl-2-pyrrolidone (NMP) and its presence in plasma and urine can be used as a biomarker of exposure to NMP

General Description

N-Methylsuccinimide is a metabolite of N-methyl-2-pyrrolidone (NMP) and its presence in in plasma and urine can be used as a biomarker of exposure to NMP. Hydrogen bonded complexes between N-methylsuccinimide and phenols (pKa = 10.2 → 6) are investigated by infrared spectrometry.
