Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients for crop protection agents. Its aldehyde functional group allows for easy modification in organic reactions, making it valuable in constructing nitrogen-containing heterocyclic compounds. It is also employed in the preparation of pyrazole-based derivatives with potential biological activity, including anti-inflammatory and antimicrobial agents. Commonly utilized in research laboratories for building complex molecules in medicinal chemistry.
