Used in pharmaceutical research as a key intermediate in the synthesis of selective receptor modulators, particularly for central nervous system targets. Its structure supports binding to neurotransmitter receptors, making it valuable in developing treatments for neurological and psychiatric disorders such as depression, schizophrenia, and cognitive impairments. Commonly employed in the design of small-molecule drugs due to its favorable pharmacokinetic properties and ability to cross the blood-brain barrier. Also utilized in the development of radiolabeled derivatives for positron emission tomography (PET) imaging studies.
