Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki and Buchwald-Hartwig aminations to build complex drug-like molecules. Also utilized in research settings for the preparation of pyridone-based derivatives with potential antiviral, anticancer, or anti-inflammatory activity.
