Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules. Its structure, with iodo at the 2-position, nitro at the 3-position, and carboxyl group on the benzene ring, allows for selective functionalization in multi-step organic reactions. The nitro group enables reduction to an amino group, which can be used in further bond-forming reactions. The iodo group supports nucleophilic substitution or copper- and palladium-catalyzed reactions, such as Ullmann or Suzuki coupling, to create more complex derivatives. Commonly employed in the preparation of heterocyclic compounds and as a building block in medicinal chemistry for introducing nitro and carboxyl functionalities. Also utilized in research settings for the development of new synthetic routes and in the modification of aromatic scaffolds for drug discovery.
