Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of fluorinated and chlorinated heterocyclic drugs. Its structure allows for selective functionalization in multi-step reactions, making it valuable in medicinal chemistry for creating analogs with enhanced biological activity. Commonly employed in the preparation of kinase inhibitors and antiviral agents due to the presence of multiple halogen atoms that can influence binding affinity and metabolic stability. Also utilized in agrochemical research for designing novel active ingredients with improved efficacy and selectivity.
