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 binding in biological systems, making it valuable in creating targeted therapies. Commonly employed in medicinal chemistry for constructing pyridine-based drug candidates due to its reactive amine group and halogen moieties, which enable further functionalization. Also utilized in the preparation of antidepressants and antiviral agents through coupling reactions and nucleophilic substitutions.
