Used in pharmaceutical research as a key intermediate in the synthesis of central nervous system (CNS) active compounds. It serves as a building block for developing drugs targeting neurological disorders such as depression, anxiety, and schizophrenia. Its structural features make it suitable for modifying receptor selectivity, particularly in serotonin and dopamine receptor ligands. Also employed in the development of PET tracers for brain imaging due to its ability to cross the blood-brain barrier. Widely utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving piperidine-based therapeutics.
