Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research related to the central nervous system. The modified piperazine structure may facilitate blood-brain barrier penetration, offering potential for developing treatments for psychiatric disorders or neurodegenerative diseases. Additionally, it is used in structure-activity relationship studies of certain enzyme inhibitors, such as carbonic anhydrase or protein kinases, involved in inflammation and cancer processes. The sulfonamide and carboxylic acid functionalities allow for derivatization and improved solubility, making it valuable in optimizing pharmacokinetic properties of active pharmaceutical ingredients.
