properties | 5-fluoro-2-nitroaniline has a melting point of 96 to 100 degrees, a boiling point of 295.5±20.0 degrees (under one atmospheric pressure), and a solid state under normal temperature and pressure. |
Use | 5-fluoro-2-nitroaniline can be used as a drug molecule and an intermediate in organic synthesis. Affected by the strong electron withdrawing of the nitro group, the fluorine atom on the benzene ring can be attacked by nucleophiles to obtain derivatized products. For example, under the attack of sodium azide, a product with an azide group at the 5th position of the benzene ring can be obtained. In addition, the nitro group can also be reduced to an amino group under the combination of tin dichloride and hydrochloric acid. |
synthesis method | 2, 4-difluoronitrobenzene (15 mmol) is dissolved in anhydrous ethanol (10 mL) in a Schlenk flask, adding 25% ammonia solution (10 mL) to the mixture, stirring the reaction mixture at room temperature and ambient temperature, the reaction progress is detected by TLC point plate; after the reaction is over, the precipitate is filtered out by diatomite, the precipitate is washed with water, and the target product 5-fluoro-2-nitroaniline is obtained by drying the precipitate in the air. |
