Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated nicotinic derivatives with potential biological activity. Its aldehyde and halogen functionalities allow for selective reactions, making it valuable in constructing heterocyclic compounds for drug discovery. Commonly employed in agrochemical research to create novel pesticides and herbicides due to its reactive scaffold. Also utilized in the preparation of fluorescent probes and organic electronic materials where fluorinated aromatic systems enhance stability and electronic properties.
