Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure allows for functionalization at the ethynyl and hydroxyl groups, enabling coupling reactions such as click chemistry or ether formation. Commonly employed in medicinal chemistry for building piperidine-based scaffolds, which are prevalent in bioactive molecules. Suitable for research into neuroactive drugs, including potential analgesics, antidepressants, or antipsychotics. Also applied in the preparation of enzyme inhibitors and receptor modulators due to the conformational rigidity provided by the substituted piperidine ring.
