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 for constructing biologically active molecules targeting inflammatory diseases and neurological disorders. Its aldehyde functional group allows for easy derivatization, enabling the formation of Schiff bases or further carbon chain extensions in drug design. Also employed in the preparation of indazole-based heterocyclic compounds with potential antimicrobial and antiviral activities.
