Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and anticancer agents. Its hydrazinyl functional group allows for easy modification to form hydrazone or azole derivatives, which are common scaffolds in drug design. Also employed in agrochemical research for creating novel pesticides due to its ability to enhance bioactivity when incorporated into heterocyclic systems. Commonly utilized in laboratory settings for building more complex pyrimidine-based molecules through condensation and cyclization reactions.
