Phenazopyridine hydrochloride appears as brick-red microcrystals with a slight violet luster or a purple powder. Aqueous solutions are yellow to brick-red and slightly acidic; they may be stabilized by the addition of 10% glucose. Slightly bitter taste. (NTP, 1992)|Phenazopyridine hydrochloride is a hydrochloride obtained by combining phenazopyridine with one equivalent of hydrochloric acid. A local anesthetic that has topical analgesic effect on mucosa lining of the urinary tract. Its use is limited by problems with toxicity (primarily blood disorders) and potential carcinogenicity. It has a role as a carcinogenic agent, a local anaesthetic and a non-narcotic analgesic. It contains a phenazopyridine(1+).|Phenazopyridine Hydrochloride is a synthetic, brick-red crystalline solid that is only slightly soluble in cold water and ethanol but is soluble in boiling water, acetic acid, glycerol, ethylene glycol and propylene glycol. It is used orally as a urinary tract analgesic. Side effects of phenazopyridine hydrochloride administration can include nausea, interference with the oxygen-carrying capacity of red blood cells (methemoglobinemia), hemolytic anemia as well as renal and hepatic toxicity. It is reasonably anticipated to be a human carcinogen. (NCI05)|A local anesthetic that has been used in urinary tract disorders. Its use is limited by problems with toxicity (primarily blood disorders) and potential carcinogenicity.Basic Info-

Reactive Group:Azo, Diazo, Azido, Hydrazine, and Azide Compounds
Reactivity Profile:PHENAZOPYRIDINE HYDROCHLORIDE is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
