Bromobenzene is primarily used as an intermediate in the synthesis of various organic compounds. It serves as a key starting material in the production of pharmaceuticals, agrochemicals, and dyes. In the pharmaceutical industry, it is utilized to create active ingredients for medications, including anti-inflammatory and antiviral drugs. Additionally, bromobenzene is employed in the manufacture of specialty chemicals, such as flame retardants and fragrances. Its role in organic synthesis also extends to the development of polymers and plastics, where it acts as a building block for more complex molecules. In research laboratories, bromobenzene is often used as a solvent or reagent in chemical reactions, particularly in Grignard reactions and coupling reactions.
