Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems. Commonly employed in medicinal chemistry for lead optimization due to the reactivity of the amino and halogen groups, enabling cross-coupling and substitution reactions. Also utilized in the preparation of biologically active compounds targeting central nervous system disorders and infectious diseases.
