Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of compounds requiring iodinated aromatic structures for further functionalization. Its iodo group allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex organic molecules. The methoxy and carboxylic acid groups provide additional sites for modification, making it valuable in medicinal chemistry for designing bioactive molecules. Also employed in research for labeling or tracer studies due to the presence of iodine.
