Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective receptor modulators. Its structure allows for functionalization at the iodine position through cross-coupling reactions, enabling the construction of complex organic molecules. Commonly employed in medicinal chemistry for creating analogs in drug discovery programs, especially those targeting central nervous system disorders and inflammatory pathways. Its seven-membered dioxepine ring provides conformational flexibility, enhancing binding affinity in certain bioactive molecules.
