Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a building block for sulfonamide-based drugs, which are commonly found in antimicrobial and anti-inflammatory agents. Its structure allows for easy modification, making it valuable in medicinal chemistry for designing molecules with improved bioavailability and target specificity. Also employed in research settings to study enzyme inhibition, especially in carbonic anhydrase inhibitors due to the presence of the sulfonamide functional group.
