Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for sulfonamide-based drugs, which are known for their antimicrobial, antiviral, and anticancer properties. The presence of multiple halogen atoms allows for further functionalization through cross-coupling reactions, making it valuable in the development of novel therapeutic agents. Also employed in agrochemical research for designing new crop protection agents due to its structural complexity and reactivity.
