Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its structural framework supports the creation of compounds with receptor affinity for neurological targets, making it valuable in research related to neurodegenerative diseases and psychiatric disorders. Also employed in the preparation of selective ligands for dopamine and serotonin receptors. Widely utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid aromatic conformation and ability to enhance binding selectivity.
