Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. It serves as a building block in the preparation of selective serotonin reuptake inhibitors (SSRIs) and other neuroactive drugs due to its structural compatibility with bioactive molecules. Its sulfone and amine functionalities allow for diverse chemical modifications, making it valuable in medicinal chemistry for optimizing drug potency, solubility, and metabolic stability. Also employed in research settings for structure-activity relationship (SAR) studies.
