yellow to orange powder | [Uses]
5-Chloro-2-nitroaniline is a useful synthetic intermediate. It can be used as a reagent to synthesize benzamide derivatives as histone deacetylase inhibitors. It is an intermediate used to synthesize 1-Nitro Febantel a Febantel impurity. | [Application]
5-Chloro-2-nitroaniline was used in the synthesis of 5-(4-substituted piperazin-1-yl)-2-nitroanilines and 5-(4-substituted piperazin-1-yl)benzimidazole-2-carbamates. The coupling of divinylbenzene cross-linked polystyrene with 5-chloro-2-nitroaniline followed by oxidative decyanation afforded benzophenone. | [General Description]
The coupling of divinylbenzene cross-linked polystyrene with 5-chloro-2-nitroaniline followed by oxidative decyanation afforded benzophenone. |
