Iodophthalein (tetraiodophenolphthalein, nosophen) is a medicinal substance . It is formed by the action of iodine on phenolphthalein and forms a yellow-white, odorless and tasteless powder that is insoluble in water and acids, soluble in ether and chloroform and melts at 225 ° C with decomposition.
It was previously used because of its non-toxicity and strong antiseptic effect, mostly as a dry powder, for wound treatment, especially in the case of extensive burns, ulcers, etc., and was also considered suitable for the treatment of syphilis .
The disodium salt of iodophthalein (antinosine) is a blue, water-soluble powder and was also used as a wound remedy, but also for the treatment of intestinal catarrh . The solution was shown to be effective against anthrax , diphtheria and pus bacteria .
Iodophthalein and iodophthalein disodium salt are among the x - ray contrast media containing iodine .
Nowadays more modern drugs are used instead of iodophthalein and its salts.
