Used as a key intermediate in the synthesis of pyrimidine-based pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its aldehyde and amino functional groups allow for easy modification, enabling the formation of hydrazone, Schiff base, and other derivatives with biological activity. It is also employed in the preparation of fluorescent probes and sensors due to its ability to undergo condensation reactions that yield conjugated systems. In medicinal chemistry research, this compound serves as a building block for constructing fused heterocyclic systems like triazines and quinazolines, which are common scaffolds in drug design.
