Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antiviral and anticancer agents. It serves as a building block in the development of pyrimidine-based drugs, which are critical in targeting specific enzyme pathways in disease treatment. Its hydrochloride form enhances solubility and stability, making it suitable for use in aqueous reaction systems. Also employed in research settings for the design of novel heterocyclic compounds with potential biological activity.
