Introduction:

Murexide (NH4C8H4N5O6, or C8H5N5O6·NH3), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid. It may be prepared by heating alloxantin in ammonia gas to 100 °C, or by boiling uramil (5-aminobarbituric acid) with mercury oxide. W. N. Hartley[1] found considerable difficulty in obtaining specimens of murexide sufficiently pure to give concordant results when examined by means of their absorption spectra, and consequently devised a new method of preparation for murexide. In this process alloxantin is dissolved in a large excess of boiling absolute alcohol, and dry ammonia gas is passed into the solution for about three hours. The solution is then filtered from the precipitated murexide, which is washed with absolute alcohol and dried. The
salt obtained in this way is in the anhydrous state. It may also be prepared by digesting alloxan with alcoholic ammonia at about 78 °C; the purple solid so formed is easily soluble in water, and the solution produced is indistinguishable from one of murexide.

Real Shot

Application&Function:
1.Complexometric indicator Indicator;

2.Murexide is used[citation needed] in analytical chemistry as a complexometric indicator for complexometric titrations, most often of calcium ions, but also for Cu, Ni, Co, Th and rare earth metals. Cf. Eriochrome Black T. Due to the minute amounts needed for this purpose, it is often used in a 1:250 mixture with potassium sulfate.

3.Murexide is also used as a colorimetric reagent for measurement of calcium and rare earth metals; for calcium, the pH required is 11.3, detection range lies between 0.2 and 1.2 ppm, and the maximum absorbance wavelength is 506 nm.
