Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and central nervous system agents. Its structure enables functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions and reductive amination processes to introduce diverse side chains for structure-activity relationship studies. Also applied in the preparation of selective serotonin reuptake inhibitors and related bioactive molecules.
