Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form stable heterocyclic structures that interact with biological targets. Commonly employed in the preparation of antiviral agents and targeted therapies where selective inhibition of enzymes is required. Its reactivity allows for functionalization at multiple sites, enabling the creation of diverse compound libraries for drug discovery.
