Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive sulfonyl chloride group and halogen functionality. The bromo and nitro groups allow for further functionalization through cross-coupling reactions and reduction, making it valuable in building complex organic molecules. Commonly employed in the development of sulfonamide-based bioactive compounds, including antimicrobial and anti-inflammatory agents. Also utilized in material science for modifying polymers and creating specialty chemicals with enhanced thermal or electronic properties.
