Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and antimicrobial agents. It serves as a building block in medicinal chemistry due to the presence of the sulfonamide group, which is commonly found in bioactive molecules. Its chlorinated aromatic structure enhances its utility in cross-coupling reactions for drug design. Also investigated for use in agrochemicals and as a precursor in the preparation of sulfonamide-based enzyme inhibitors.
