Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure supports modification for neuroactive drugs, including those targeting cognitive disorders and neurological conditions. The presence of both alkyne and carboxylic acid functional groups allows for versatile coupling reactions, making it valuable in medicinal chemistry for building complex molecules through click chemistry or peptide coupling techniques. It is also employed in research settings to design novel receptor ligands, especially for neurological receptors such as sigma or NMDA receptors.
