Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. Its structure supports the creation of bioactive molecules with potential antipsychotic, antidepressant, or cognitive-enhancing effects. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid, nitrogen-containing ring system. Also utilized in the preparation of enzyme inhibitors and receptor modulators, especially targeting GPCRs and kinases. Its amine functionality allows for easy derivatization, making it valuable in combinatorial chemistry and drug discovery pipelines.
