Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules due to the presence of amine functionalities that can participate in various coupling reactions. Commonly employed in the preparation of serotonin and norepinephrine reuptake inhibitors, making it valuable in the research and production of antidepressants and anxiolytic drugs. Also utilized in the design of receptor ligands where a rigid, polar scaffold enhances binding affinity and selectivity. Its water solubility, especially in salt form, improves handling in aqueous reaction conditions and formulation processes.
