Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antituberculosis agents. It serves as a building block for pyridine-based compounds that exhibit biological activity, including kinase inhibitors and antimicrobial drugs. Its amino and carboxylic functional groups allow for easy modification in multi-step organic syntheses, making it valuable in medicinal chemistry research. Also employed in the preparation of ligands for catalytic processes and in the design of heterocyclic compounds for drug discovery.
