2-Bromochlorobenzene is a chemical compound that belongs to the group of brominated aromatic compounds. It is used as an intermediate in organic synthesis, often as a precursor to pyrazoles. 2-Bromochlorobenzene can be synthesized by reacting hydrochloric acid with benzene and chloroform in the presence of sodium nitrite. The reactants are heated at temperatures between 50 and 60 °C for 3 hours. This reaction mechanism is shown below: 2-Bromochlorobenzene also reacts with diazonium salt to form an unstable intermediate that decomposes into bromine and chloride ions, which react with each other to form 2-bromochlorobenzene and hydrochloric acid. The reaction solution contains hydrogen chloride gas, which can be removed by bubbling it through water. Chromatography can be used to isolate 2-bromochlorobenzene from the reaction solution by passing
