Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active compounds. Its halogen substituents allow for selective cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex pyridine-based structures. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the ease of functionalization at the bromo and iodo positions. Also utilized in the preparation of ligands for catalysis and in the design of fluorescent probes or imaging agents where the carboxylic acid group can be conjugated to other molecules.
