Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and analgesics. It serves as a building block for modifying molecular structures to enhance bioavailability and receptor selectivity. Its sulfonamide and amine functionalities allow for hydrogen bonding and improved solubility, making it valuable in drug design. Also employed in the preparation of enzyme inhibitors due to its ability to mimic transition states in metabolic pathways.
