Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating biologically active molecules. Commonly employed in medicinal chemistry research for constructing pyridine-based drug candidates. Also utilized in the preparation of labeled compounds for metabolic studies and in the design of PET tracers due to the presence of the bromine atom, which facilitates radiolabeling.
