Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of dyes and fluorescent probes due to its aromatic structure and bromine functionality. Its carboxylic acid group allows for easy derivatization, making it valuable in organic synthesis for coupling reactions. Also employed in the preparation of ligands for metal catalysts and in materials science for modifying surface properties. The presence of the bromine atom enables further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, expanding its utility in creating complex organic molecules.
