Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for effective binding in biologically active molecules, making it valuable in medicinal chemistry. Commonly employed in research settings to construct more complex heterocyclic systems. Also utilized in the preparation of selective modulators for neurological targets due to its ability to cross the blood-brain barrier. Frequently appears in synthetic routes for drug candidates in oncology and central nervous system disorders.
