Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for creating analogs with optimized biological activity. It is also employed in the preparation of receptor ligands targeting neurological disorders such as depression, anxiety, and Parkinson’s disease. Additionally, it serves as a building block in the creation of novel heterocyclic compounds for drug discovery research.
