Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its sulfonamide group and bromine substituent make it suitable for cross-coupling reactions, enabling the construction of complex aromatic compounds. Commonly employed in the preparation of bioactive molecules where the diethylsulfonamide moiety enhances solubility and binding properties. Also utilized in research settings for the synthesis of sulfonamide-based inhibitors targeting enzymes such as carbonic anhydrases.
