One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 930-88-1, Name is 1-Methyl-1H-pyrrole-2,5-dione, formurla is C5H5NO2.

Synthesis and herbicidal activity of novel 3-alkoxycarbonyl-3-aryl-2, 3-dihydro-2-oxo-1H-pyrrole derivatives
In the course of efforts to find novel compounds with improved crop safety in transplanted rice by the modification of 1-[1-(3,5 -dichlorophenyl)-1-methylethyl]-4-methyl-3-phenyl-3-pyrrolin-2-one (1a), which was reported to have excellent herbicidal activity against paddy weeds, 2,3-dihydro-2-oxo-1H-pyrrole derivatives with a quaternary carbon atom having an alkoxycarbonyl group at the alpha-position of the cyclic amide were synthesized and examined. Among these compounds, methyl 1-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-4-methyl-2-oxo-3-phenyl-1H-pyrrole-3-carboxylate (2a) was not only active against Echinochloa oryzicola and Scirpus juncoides but also compatible with transplanted rice even in harsh conditions. On the bask of Preliminary experimental results. it was thought that 2a would generate the corresponding 2-oxo-3-pyrrolin (la) through the metabolic degradation of the methoxycarbonyl moiety.
