Used in pharmaceutical research as a key intermediate in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure supports the development of compounds targeting neurological disorders such as depression and anxiety. The hydrochloride salt form enhances solubility and stability, making it suitable for preclinical formulation studies. Also explored in medicinal chemistry for optimizing bioavailability and receptor binding affinity in novel drug candidates.
