Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure supports the formation of bioactive molecules due to the presence of functional groups like the ethynyl and hydroxyl moieties, which allow for further chemical modifications. Commonly employed in medicinal chemistry for constructing piperidine-based drug candidates, especially those targeting neurological disorders. Also utilized in research settings for building complex heterocyclic systems through coupling reactions and cyclizations.
