Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports the construction of pyrimidine-based drugs, which are common in treatments for cancer, inflammatory diseases, and viral infections. The amino and ester functional groups allow for easy modification, making it valuable in medicinal chemistry for creating compound libraries during drug discovery. Also employed in the preparation of agrochemicals and functional materials due to its heterocyclic framework.
