Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of fluorinated and brominated aromatic compounds. Its functional groups enable selective reactions, making it valuable in building complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form carbon-carbon bonds. Also utilized in the preparation of dyes, fluorescent probes, and specialty materials where nitro and aldehyde functionalities are needed for further derivatization.
