Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in organic reactions where selective halogen substitution enables the formation of complex molecules. Its iodo and chloro functional groups allow for cross-coupling reactions, making it valuable in medicinal chemistry for creating targeted derivatives. Also employed in research settings to develop new bioactive agents and enzyme inhibitors.
