Also known as 4,4'-diisothiocyanostilbene-2,2'-disulphonic acid, 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid, ABC inhibitor 2, 2,2'-ethene-1,2-diylbis(5-isothiocyanatobenzenesulfonic acid), 4,4'-diisothiocyano-2,2'-stilbenedisulfonic acid, 4,4'-diisothiocyanato-2,2'-stilbenedisulfonic acid

4,4′-Diisothiocyano-2,2′-stilbenedisulfonic acid (DIDS) is an anion exchange inhibitor, blocking reversibly, and later irreversibly, exchangers such as chloride-bicarbonate exchanger.
