Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of sulfonamide-based compounds. Its reactive sulfonyl chloride group allows for easy attachment to amines or alcohols, forming sulfonamides or sulfonate esters, which are key structures in many bioactive molecules. The bromine at the 4-position and fluorine at the 3-position on the benzene ring enhance solubility and binding affinity to biological targets, making it valuable in creating potent drug candidates. Commonly employed in medicinal chemistry for constructing enzyme inhibitors and receptor ligands. Also utilized in the preparation of functionalized aromatic compounds for research in organic synthesis and drug discovery.
