Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of bioactive compounds targeting neurological disorders, including depression and anxiety. Also utilized in the creation of fluorinated analogs to enhance metabolic stability and binding affinity in drug candidates.
