Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of pyrazole-based bioactive compounds. Its aldehyde functional group allows for easy modification, making it valuable in constructing heterocyclic systems for drug discovery. It is also employed in the preparation of dyes and functional materials due to its aromatic and electron-rich structure. Commonly utilized in research laboratories for building blocks in organic synthesis and coordination chemistry with metal ions.
