Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anxiolytic and sedative agents. Its structure supports the formation of bioactive molecules that interact with central nervous system receptors. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocyclic compounds with potential therapeutic activity. Also utilized in the preparation of fluorescent probes and optoelectronic materials due to its conjugated aromatic system. Serves as a building block in combinatorial chemistry for drug discovery and in the creation of libraries for biological screening.
