Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrimidine-based drugs which exhibit antiviral, anticancer, and antimicrobial activities. It serves as a building block in the preparation of fused heterocyclic compounds, including barbiturate derivatives and other bioactive molecules. Its aldehyde and amino functional groups allow for versatile chemical modifications, enabling the formation of Schiff bases, hydrazones, and other derivatives important in medicinal chemistry research. Also employed in the design of dyes and functional materials due to its conjugated structure and reactivity.
