Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure supports the creation of bioactive molecules due to the presence of both a reactive alkyne group and a carboxylic acid functionality, enabling diverse chemical modifications. The terminal alkyne allows for efficient click chemistry reactions with azides to form triazole linkages. Commonly employed in medicinal chemistry for constructing piperidine-based drug candidates, especially those targeting neurological disorders. Also utilized in the preparation of analogs for structure-activity relationship studies.
