Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with potential antimicrobial and anti-inflammatory properties. It serves as a building block in organic reactions where the chlorophenyl and sulfonamide groups are key structural elements for further functionalization. Also explored in agrochemical research for designing novel bioactive molecules. Its reactivity allows for coupling reactions in medicinal chemistry pathways to create more complex therapeutic agents.
