Application

4-Iodobenzenesulfonic acid hydrazide serves as a key building block in medicinal chemistry for the development of sulfonamide-based drugs. Researchers employ it in Pd-catalyzed cross-coupling reactions (e.g., Suzuki-Miyaura) to create biaryl structures. Its reactive hydrazide group facilitates the synthesis of heterocycles and Schiff bases. The compound is also investigated as a precursor for radiopharmaceutical labeling due to the iodine moiety’s potential for isotopic exchange.
