Used as a key intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in the development of kinase inhibitors and other targeted therapies. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in peptide modification and conjugation strategies due to the reactive amine group and activated dicarbonyl system. Also utilized in the preparation of fluorescent probes and labeling agents for biochemical assays.
