Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of antibacterial and antiviral drugs. Its structure supports the design of inhibitors targeting specific enzymes in pathogenic microorganisms. Commonly employed in medicinal chemistry for constructing fused heterocyclic systems that enhance drug potency and selectivity. Also utilized in research settings to develop novel kinase inhibitors and anti-inflammatory compounds. Its functional groups allow for easy derivatization, making it valuable in structure-activity relationship (SAR) studies.
