Used in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators, particularly targeting 5-HT3 receptors. Its structure supports the development of compounds with potential applications in treating neurological and psychiatric disorders such as anxiety, depression, and nausea associated with chemotherapy. The carboxylic acid and pyrrolidine functional groups allow for versatile chemical modifications, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in the design of novel ligands for central nervous system targets due to its favorable binding properties and structural rigidity.
