Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and central nervous system (CNS) active agents. Its structure supports the formation of biologically active molecules with potential antitumor, anti-inflammatory, and neuroprotective properties. Commonly employed in medicinal chemistry for scaffold modification and drug optimization due to its rigid, aromatic framework and favorable binding characteristics. Also utilized in the preparation of fluorescent probes and materials for organic electronics owing to its conjugated system and stability.
