Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its halogen substituents allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in Suzuki and Heck reactions to introduce aryl or vinyl groups during drug discovery processes. Also utilized in the preparation of pyridone-based derivatives with potential antiviral or anticancer activity.
