Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its spirocyclic structure and fluorinated aromatic ring make it valuable in medicinal chemistry for enhancing metabolic stability and binding affinity. Commonly employed in the preparation of selective enzyme inhibitors and receptor modulators, especially in research targeting neurological disorders. The compound’s rigid framework supports conformational restriction strategies, improving selectivity and potency in drug candidates.
