Used in pharmaceutical research as a key intermediate for developing bioactive compounds, particularly in the synthesis of potential antitumor and antimicrobial agents. Its fused heterocyclic structure enhances binding affinity to specific enzyme targets, making it valuable in drug discovery. Also investigated for its role in kinase inhibition, which is relevant in treating inflammatory diseases and certain cancers. Additionally, it serves as a scaffold in medicinal chemistry for optimizing lead compounds due to its metabolic stability and structural specificity.
