Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihistamines and antidepressants. It serves as a building block in the development of drugs that modulate central nervous system activity. Its structure allows for interaction with neurotransmitter transporters, making it valuable in the design of compounds affecting serotonin, norepinephrine, and dopamine reuptake. Also utilized in research settings to develop novel analogs for therapeutic evaluation.
