Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the design of bioactive molecules targeting specific signaling pathways in tumor cells. Commonly employed in medicinal chemistry research to optimize drug candidates due to its favorable reactivity and ability to enhance binding selectivity. Also utilized in the preparation of fluorinated and brominated heterocyclic compounds, which are important in improving metabolic stability and pharmacokinetic properties of new drug entities.
