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 (CNS) active agents. Its structure allows for effective binding to specific receptors, making it valuable in creating drugs that regulate neurotransmitter activity. Commonly employed in medicinal chemistry for optimizing drug potency and metabolic stability. Also utilized in research settings to develop novel analogs with improved pharmacokinetic profiles.
