Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antipsychotic drugs. It serves as a building block in the preparation of more complex molecules due to the presence of both aldehyde and pyrrolidine functional groups, enabling diverse chemical transformations. Commonly employed in medicinal chemistry for structure-activity relationship studies and the optimization of drug candidates. Also utilized in the production of agrochemicals and specialty organic compounds requiring functionalized aromatic frameworks.
