Used primarily in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds. It serves as a structural scaffold in the development of central nervous system agents, particularly those targeting neurological disorders such as depression, anxiety, and epilepsy. Its spirocyclic structure enhances stereochemical stability, making it valuable in designing selective receptor modulators. Also employed in medicinal chemistry for optimizing drug candidates due to its favorable pharmacokinetic properties and ability to cross the blood-brain barrier.
