Application of 1127-59-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1127-59-9, name is 7-Methylindoline-2,3-dione, This compound has unique chemical properties. The synthetic route is as follows.
Step 3: 5-bromo-7-methylindoline-2,3-dioneTo a stirred mixture of 7-methylindoline-2,3-dione (7 g, 0.043 mol) in chloroform (700 mL) was added a solution of bromine (2.8 mL, 0.053 mol) in chloroform (100 mL) dropwise over 15 min at room temperature. The reaction mixture was heated at 80°C for 24 h and then cooled to 0°C, which resulted in precipitation of the product as a red solid. The solid was collected by suction filtration and dried under vacuum to afford the title compound (8 g, 77percent).XH NMR (400 MHz, DMSO-d6) : delta 11.20 (s, 1H), 7.64 (d, J = 1.2 Hz, 1H), 7.42 (d, J = 7.2 Hz, 1H), 2.18 (s, 3H); ESI-MS: Calculated mass: 238.96; Observed mass: 238.30 [M-H]”.
The chemical industry reduces the impact on the environment during synthesis 7-Methylindoline-2,3-dione. I believe this compound will play a more active role in future production and life.
