Preparation of 3-Bromophenol: it is prepared by diazotization, bromination reaction of m-aminool. Firstly, m-aminool is dissolved in sulfuric acid, cooled to 10 °C. Then adding aqueous solution of sodium nitrite to the solution for diazotization reaction. Secondly, filtrate is hydrolyzed with CuBr after filtration. At last, collecting steamed liquid and product is obtained by filtration, extraction, drying and distillation.

Uses of 3-Bromophenol: it is used to produce benzoic acid-(3-bromo-phenyl ester) by reaction with benzoyl chloride. The reaction occurs with reagent triethylamine and solvent CH₂Cl₂ at the temperature of 20 °C for 30 minutes. The yield is about 75%.
