| 4-Bromoaniline Usage And Synthesis |
Chemical Properties | brown crystals | Uses | 4-Bromoaniline is used as a precursor in the production of azo dyes and dihydroquinazolines. It is also used as carbon and nitrogen supplement in the culture medium of Moraxella sp. strain G. Further, it is employed in the preparation of para-bromobiphenyl through Gomberg-Bachmann reaction. In addition to this, it is used as a building block in the preparation or pharmaceutical and organic compounds. | Uses | 4-Bromoaniline is a brominated aniline that is commonly used as a building block in the preparation of pharmaceutical and organic compounds. It is used in the preparation of azo dyes and is condensed with formaldehyde to prepare dihydroquinazolines. In addition, 4-Bromoaniline is also used as an intermediate in the production of other chemicals such as metobromuron, a herbicide, and resorantel, an antiparasitic agent. | Preparation | 4-bromoaniline can be made by reacting aniline with bromine with a protection with acetyl chloride. | Synthesis Reference(s) | The Journal of Organic Chemistry, 40, p. 1867, 1975 DOI: 10.1021/jo00900a053 Synthetic Communications, 19, p. 3047, 1989 DOI: 10.1080/00397918908052699 | General Description | P-bromoaniline is a brown solid with a sweet odor. (NTP, 1992) | Air & Water Reactions | 4-Bromoaniline is sensitive to prolonged exposure to air. Vapor may form highly reactive mixtures in air . Insoluble in water. | Reactivity Profile | Vapor may form highly reactive mixtures in air. | Fire Hazard | Flash point data are not available for 4-Bromoaniline, but 4-Bromoaniline is probably combustible. | Purification Methods | Crystallise the aniline (with appreciable loss) from aqueous EtOH. The benzoyl derivative has m 204o (from EtOH). [Beilstein 12 IV 1497.] |
