Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nitrogen-containing heterocyclic compounds with potential biological activity. Its alkyne functionality allows for use in click chemistry reactions, enabling efficient coupling with other molecular fragments in drug discovery. Also employed in agrochemical research for designing novel pesticides and herbicides due to its ability to enhance binding affinity with target enzymes. Its aromatic structure supports conjugation in materials science, especially in the development of organic semiconductors and fluorescent probes.
