Bromobenzene is primarily used as an intermediate in the synthesis of various organic compounds. It plays a key role in the production of pharmaceuticals, agrochemicals, and dyes. In the pharmaceutical industry, it is utilized to manufacture drugs such as antihistamines and analgesics. Additionally, bromobenzene is employed in organic synthesis as a precursor for Grignard reagents, which are essential for forming carbon-carbon bonds. It is also used in the preparation of specialty chemicals and as a solvent in certain industrial processes. However, its use is carefully regulated due to its toxic and hazardous nature.
