E239 was first introduced into the medical setting in 1899 as a urinary antiseptic. However, it was only used in cases of acidic urine, whereas boric acid was used to treat urinary tract infections with alkaline urine. Scientist De Eds found that there was a direct correlation between the acidity of E239 environment and the rate of its decomposition. Therefore, its effectiveness as a drug depended greatly on the acidity of the urine rather than the amount of the drug administered. In an alkaline environment, E239 was found to be almost completely inactive.
E239 was also used as a method of treatment for soldiers exposed to phosgene in World War I. Subsequent studies have shown that large doses of E239 provide some protection if taken before phosgene exposure but none if taken afterward.
