Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of anti-inflammatory and anticancer agents. Its fused furo-pyrimidine core structure shows promise in modulating enzyme activity, especially in kinase inhibition pathways. It is also employed in the design of novel antimicrobial agents due to its ability to interfere with microbial nucleic acid synthesis. The chloromethyl group allows for further functionalization, making it valuable in structure-activity relationship (SAR) studies during drug optimization.
