Used in the synthesis of pharmaceutical intermediates, particularly in the development of kinase inhibitors and other bioactive molecules. Its halogenated structure makes it suitable for cross-coupling reactions, such as Suzuki or Buchwald-Hartwig reactions, enabling the construction of complex aromatic systems in drug discovery. Also employed as a building block in agrochemicals and functional materials where substituted pyridine derivatives are required. The carboxylic acid group allows for easy derivatization into amides, esters, or other functional groups to tune solubility and reactivity in synthetic pathways.
