Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. The sulfonamide group enhances solubility and can participate in hydrogen bonding, making it useful in the design of bioactive molecules. It is also employed in the preparation of sulfonamide-based drugs, where structural modifications improve efficacy or pharmacokinetic properties.
