Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders and anti-inflammatory agents. Its structure supports the development of heterocyclic compounds with potential anticonvulsant and analgesic properties. Also employed in the preparation of fluorescent dyes and optoelectronic materials due to its conjugated system and electron-rich nature. Commonly utilized in medicinal chemistry for scaffold modification to enhance drug potency and selectivity.
