Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals. It serves as a chiral building block in the preparation of bioactive molecules due to the presence of a stereogenic center. Its sulfonamide and carboxylic acid functional groups allow for further derivatization, making it valuable in medicinal chemistry for designing enzyme inhibitors or receptor ligands. Also employed in the synthesis of peptidomimetics and other heterocyclic compounds with potential therapeutic activity.
