4,5-Dichloro-1,3-benzenedisulfonyl Dichloride-13C6 is an intermediate used in the synthesis of Diclofenamide-13C6 (D436532), which is the labeled form of Diclofenamide, a potent carbonic anhydrase inhibitor. Diclofenamide may provide a therapeutic strategy in the inhibition of the human cytosolic isoforms I and II and transmembrane tumor-associated isoenzymes IX and XII. Diclofenamide has been shown to be is effective in the prevention of episodic weakness in both hypokalemic periodic paralysis (HypoPP) and potassium-sensitive periodic paralysis (PSPP).
