Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where brominated aromatic compounds serve as coupling partners in cross-coupling reactions such as Suzuki or Heck reactions. The presence of both carboxylic acid and ester functional groups allows for selective derivatization, enabling the construction of complex molecules. Commonly employed in research settings for the preparation of substituted aromatic compounds with potential biological activity. Also utilized in the production of specialty polymers and agrochemicals requiring specific substitution patterns on aromatic rings.
