Used as a key intermediate in the synthesis of fluorinated and iodinated aromatic compounds, particularly in pharmaceuticals and agrochemicals. Its structure allows for selective functionalization in drug development, especially in creating kinase inhibitors and radiolabeled compounds for medical imaging. The presence of both amino and carboxylic acid groups enables peptide coupling, making it useful in building complex bioactive molecules. Also employed in the preparation of fluorescent probes and specialty dyes due to its halogen substitution pattern.
