Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anti-inflammatory agents. Its scaffold is valued in medicinal chemistry for enabling strong binding to biological targets due to its planar, heterocyclic structure. Commonly found in research related to central nervous system disorders and oncology, where it helps modulate enzyme activity and signal transduction pathways. Also employed in the design of fluorescent probes and bioactive molecules due to its favorable photophysical properties and metabolic stability.
