Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of kinase inhibitors. It serves as a building block in medicinal chemistry for designing molecules with potential anti-inflammatory, anticancer, and antiviral properties. Its structure allows for easy functionalization, making it valuable in creating compound libraries for drug discovery. Also employed in the preparation of PROTACs (proteolysis-targeting chimeras) due to its ability to link targeting moieties with E3 ligase ligands.
