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 investigated for use in positron emission tomography (PET) tracers due to its ability to cross the blood-brain barrier. Additionally, it serves as a building block in the design of kinase inhibitors for cancer therapy.
