Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of analgesic and anti-inflammatory agents. It serves as a building block in heterocyclic chemistry, enabling the creation of more complex pyrazole derivatives with potential biological activity. Also employed in research for developing new dyes and fluorescent probes due to its aromatic and electron-donating structure. Its amino group allows for easy functionalization, making it valuable in combinatorial chemistry and drug discovery.
