Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules that target central nervous system disorders. Its structure allows for selective modification of nitrogen-containing heterocycles, making it valuable in medicinal chemistry for creating analogs with improved pharmacokinetic properties. Commonly employed in the preparation of selective receptor ligands and enzyme inhibitors due to the presence of reactive functional groups that facilitate coupling reactions. Also utilized in solid-phase synthesis and combinatorial chemistry for generating compound libraries in drug discovery.
