Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a building block in the preparation of bioactive molecules due to the presence of both a carboxylic acid and a sulfonyl group, which can be further modified. Its structure is useful in medicinal chemistry for designing enzyme inhibitors or receptor modulators, especially in research targeting neurological or inflammatory pathways. Also employed in the synthesis of sulfa drugs and other sulfonamide-based therapeutics.
