Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active compounds. Its structure supports the creation of agents with potential antidepressant and anxiolytic effects. The compound is also utilized in the preparation of selective serotonin reuptake inhibitors (SSRIs) and related psychotropic drugs. Due to the presence of the trifluoromethylthio group, it enhances metabolic stability and lipophilicity, improving blood-brain barrier penetration. It finds application in medicinal chemistry research for optimizing drug candidates targeting neurological disorders.
