Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anti-inflammatory agents. It serves as a building block in heterocyclic chemistry, enabling the construction of complex nitrogen-containing rings found in biologically active molecules. Its amino and carboxylic functional groups allow for easy modification, making it valuable in medicinal chemistry for drug discovery and optimization. Also employed in the preparation of agrochemicals and dyes due to its reactivity and structural versatility.
