Used primarily in research settings as an intermediate in the synthesis of biologically active compounds, particularly in the development of potential anti-cancer pharmaceutical agents. This compound exhibits inhibitory activity against proteins involved in cancer cell division and disrupts DNA replication in abnormal cells. Its fused pyrido[1,2-a]pyrimidine ring system serves as a building block in heterocyclic chemistry, supporting derivatization to enhance binding affinity and selectivity in medicinal chemistry applications. Limited to laboratory use with no widespread industrial or commercial applications reported.
