Used 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 bromine functionality allows for further derivatization via cross-coupling reactions, making it valuable in medicinal chemistry and drug discovery. Also employed in the synthesis of dyes and functional materials where sulfonamide groups enhance solubility and binding properties.
