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 targeted therapies. Commonly employed in research settings to build more complex heterocyclic systems with biological activity. Also utilized in the preparation of PROTACs (proteolysis-targeting chimeras) due to its ability to bind effectively with target proteins. Shows promise in medicinal chemistry for designing drugs with improved binding affinity and metabolic stability.
