Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of fluorinated and brominated heterocyclic drugs. Its structure allows for selective functionalization in ring-forming reactions, making it valuable in creating active pharmaceutical ingredients (APIs) with enhanced metabolic stability and binding affinity. Commonly employed in the preparation of kinase inhibitors and antitumor agents due to the presence of halogen atoms that facilitate cross-coupling reactions. Also utilized in agrochemical research for designing novel bioactive molecules.
