Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its bromine functionality allows for cross-coupling reactions, enabling the construction of complex aromatic systems. Commonly employed in the preparation of sulfonamide-based bioactive molecules due to the stability and polarity imparted by the sulfonamide group. Also utilized in medicinal chemistry for structure-activity relationship studies, where the bromo substituent serves as a site for further functionalization or as a radiolabeling handle in tracer studies.
