Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly those targeting central nervous system disorders. It plays a key role in the development of selective serotonin reuptake inhibitors (SSRIs) and other neuropsychiatric medications. Its structure allows for modifications that enhance binding affinity to neurotransmitter receptors, making it valuable in drug discovery. Also investigated for potential applications in treating cognitive impairments and neurodegenerative diseases due to its ability to cross the blood-brain barrier effectively.
