Phenazopyridine compound
WebThe most important application of diazo coupling reactions is electrophilic aromatic substitution of activated benzene derivatives by diazonium electrophiles. The products of such reactions are highly colored aromatic azo compounds that find use as synthetic dyestuffs, commonly referred to as azo dyes. WebPhenazopyridine may induce methemoglobinemia. Erythrocytes possess four hemoglobin chains, each of which contains a heme moiety. Methemoglobin occurs when phenazopyridine induces oxidation of the heme moiety, changing the normal oxygen-carrying ferrous (Fe2+) state to the ferric (Fe 3+) state. Ferric heme is incapable of …

Phenazopyridine is a medication which, when excreted by the kidneys into the urine, has a local analgesic effect on the urinary tract. It is often used to help with the pain, irritation, or urgency caused by urinary tract infections, surgery, or injury to the urinary tract. Phenazopyridine was discovered by Bernhard Joos, the founder of Cilag. WebAzo groups are chemical compounds with the general formula R-N=N-R', where R and R' can be either aryl (aromatic) or alkyl (aliphatic) functional groups. The N=N group is called an azo group, although the parent compound, HN=NH, is called diamide. The stable azo compounds contain two aryl groups.
