Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of biologically active compounds, particularly in the development of drug candidates targeting central nervous system disorders and anti-inflammatory agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Also employed in the synthesis of fluorescent dyes and optoelectronic materials due to its conjugated aromatic framework.
