Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block for dopamine and serotonin receptor modulators, which are relevant in treating neurological and psychiatric disorders such as depression, anxiety, and Parkinson’s disease. Its structure allows for selective binding and improved metabolic stability in drug candidates. Also employed in the preparation of chiral catalysts and ligands for asymmetric synthesis in medicinal chemistry research.
