Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block for compounds with antihistaminic, antipsychotic, and antidepressant properties. Due to its structural features, it is also employed in the preparation of receptor ligands, especially those targeting dopamine, serotonin, and histamine receptors. Commonly found in research settings for drug discovery and optimization of bioactive molecules.
