Chemical Properties

Formula Weight
Melting point
ca 230° dec.
Storage & Sensitivity
Light Sensitive. Ambient temperatures.
Insoluble in water.


1-Organosulfonyloxy-1, 2-benziodoxol-3-(1H)-ones (3, 4, 5) can be prepared in one step from 2-iodosobenzoic acid and the corresponding sulfonic acids. 2-carboxydiphenyliodonium salts was prepared by the acid-catalyzed condensation of 2-iodosobenzoic acid with benzene, mesitylene, and cyclohexylbenzene.


Light Sensitive. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, light.
