Used primarily as an intermediate in organic synthesis, particularly in the preparation of sulfonamide-based pharmaceuticals. It serves as a building block in the development of bioactive molecules, including antimicrobial and anti-inflammatory agents. Its sulfonamide group enables hydrogen bonding and polarity, making it valuable in drug design for enhancing solubility and target binding. Also employed in the synthesis of agrochemicals and functional materials where stable, polar moieties are required.
