Used as an intermediate in organic synthesis, particularly in pharmaceutical development. It serves as a building block for modifying piperidine-based structures, which are common in drug molecules targeting central nervous system disorders. The presence of the methylsulfonyl oxy group makes it suitable for nucleophilic substitution reactions, enabling the introduction of various functional groups. Commonly applied in the preparation of protease inhibitors and receptor antagonists. Also utilized in research settings for constructing complex heterocyclic systems through selective alkylation or cyclization processes.
