Used in medicinal chemistry as a key intermediate for synthesizing bioactive compounds, particularly in the development of fluorescent probes and sensors due to its electron-deficient heterocyclic core. Its structure supports conjugation with biomolecules for imaging applications in cellular systems. Also explored in the design of kinase inhibitors and other therapeutic agents where enhanced binding affinity and selectivity are required. Shows utility in materials science for creating luminescent materials and optoelectronic devices.
