Used primarily in pharmaceutical research as an intermediate in the synthesis of centrally acting agents, particularly those targeting the central nervous system. It serves as a building block in the development of cognitive enhancers and neurological therapeutics. Its structure supports binding to neurotransmitter receptors, making it valuable in the design of drugs for neurodegenerative disorders such as Alzheimer's and Parkinson's disease. Also investigated for use in compounds with potential anxiolytic and antidepressant effects. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its favorable pharmacokinetic properties and ability to cross the blood-brain barrier.
