Used primarily as an intermediate in the synthesis of certain tricyclic antidepressant medications. It plays a key role in the production of drugs that modulate neurotransmitter activity in the central nervous system, particularly those targeting depression and anxiety disorders. Due to its reactive hydroxyl and chlorine groups, it allows for further chemical modifications to build complex pharmacologically active molecules. Its structure supports binding affinity to neural receptors, making it valuable in developing psychotropic agents.
