| | 3-chloro-5-nitro-aniline Usage And Synthesis |
| Synthesis | General procedure for the synthesis of 3-chloro-5-nitroaniline from 1-chloro-3,5-dinitrobenzene: 1-chloro-3,5-dinitrobenzene (0.50 g, 2.47 mmol) was dissolved in a mixed solvent of 6 mL of ethanol and 3 mL of 20% aqueous ammonium sulphide, and the reaction was carried out at reflux for 1 hour. After completion of the reaction, diluted by adding appropriate amount of water, filtered to collect the solid product and dried. The product was purified by rapid chromatography on silica gel column using 10% acetone-petroleum ether mixed solvent as eluent, and finally 3-chloro-5-nitroaniline (0.36 g, 84% yield) was obtained as an orange powder. | | References | [1] Patent: US6353013, 2002, B1.
