Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its unique halogenated structure enhances binding selectivity to specific enzyme targets. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of multiple halogens that influence metabolic stability and lipophilicity. Also utilized in the preparation of radiolabeled compounds for positron emission tomography (PET) imaging research.
