1. Introduction of 3-Bromonitrobenzene
3-Bromonitrobenzene with the CAS registry number 585-79-5, is also named as m-Bromonitrobenzene. The IUPAC name of 3-Nitrobromobenzene is 1-bromo-3-nitrobenzene. The product's categories are Aromatic Halides (substituted); Benzene Derivates; Bromine Compounds; Nitro Compounds; Nitrogen Compounds; Organic Building Blocks. 3-Bromonitrobenzene is white to light yellow crystal powder which is soluble in alcohol, benzene and ether, insoluble in water. When heated to decomposition it emits toxic vapors of NO_x and Br⁻. So the storage environment should be well- ventilated, low-temperature and dry. Keep 3-Nitrobromobenzene separate from raw materials of food.

5. Preparation of 3-Bromonitrobenzene
3-Bromonitrobenzene can be obtained by the bromination of nitrobenzene. Adding nitrobenzene, iron powder (half volume) and carbon tetrachloride into reactor. Heating to 120 °C and dropping bromine (1 / 3 volume) in 2h. And then replenishing bromine and iron powder twice that the temperature is at 120-135 °C. Controlling this temperature and stirring 3h. Using steam distillation to collect grease. And cooling to get yellow solid. Finally, using ethanol to get the product.

6. Use of 3-Bromonitrobenzene
3-Bromonitrobenzene is used as intermediate in organic synthesis. In pharmaceutical industry, it is used to synthetize of 1-amino-3-bromobenzene and produce hypnotic, sedative and antiemetic medicines. It also can react with 5-bromo-nicotinic acid methyl ester to get 5-(3-nitro-phenyl)-nicotinic acid methyl ester. This reaction needs reagent Copper bronze, catalytic agent Pd(OAc)₂, tri-o-tolylphosphine, NEt₃, and solvent dimethylformamide at temperature of 180 °C. The reaction time is 8 hours. The yield is 40%.
