Used in pharmaceutical research as a key intermediate in the synthesis of central nervous system (CNS) active compounds, particularly in the development of serotonin and dopamine receptor modulators. Its structure supports the creation of novel azepine-based therapeutics for treating neurological disorders such as anxiety, depression, and schizophrenia. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid scaffold and functional group compatibility. Also utilized in the preparation of radiolabeled derivatives for receptor binding assays and imaging studies.
