Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted aromatic structures. Its bromine functionality allows for coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex organic molecules. Also employed in the preparation of specialty chemicals where carboxylic acid and halogen groups are needed for further derivatization. Its ethyl and carboxyl groups contribute to solubility and binding properties in designed molecules.
