Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its halogenated structure allows for selective cross-coupling reactions, enabling the introduction of various functional groups during drug optimization. Commonly employed in research settings to design potent and selective small molecule therapeutics targeting tyrosine kinases and other signaling proteins involved in tumor growth and inflammation. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid heterocyclic scaffold.
