Tetrasodium 1,3,6,8-pyrenetetrasulfonate is a highly water-soluble derivative of pyrene, a polycyclic aromatic hydrocarbon
The compound can be synthesized in one step by treating pyrene with 50% oleum and sodium sulfate. A traditional two-step method was treating the pyrene with sulfuric acid and sodium sulfate and then treating it with 60% oleum and sodium sulfate.
