Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective enzyme inhibitors and receptor antagonists. Its structure supports the design of bioactive molecules with improved metabolic stability and binding affinity. Commonly employed in medicinal chemistry for optimizing lead compounds in drug discovery programs targeting central nervous system disorders and inflammatory conditions. The sulfonyl and carboxylic acid functional groups allow for versatile derivatization, facilitating the preparation of amides and esters to fine-tune pharmacokinetic properties.
