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 binding to neurotransmitter receptors, making it valuable in developing antidepressants and anxiolytic drugs. Also explored in the design of kinase inhibitors for potential oncology applications. The hydrochloride salt form enhances solubility and stability, beneficial for formulation in early-stage drug development.
