Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the formation of biologically active molecules that target specific enzyme pathways. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles with potential therapeutic activity. Also utilized in the preparation of fluorescent probes and sensors due to its favorable photophysical properties. Plays a role in the design of compounds for oncology and central nervous system disorders.
