Murexide Specification

The Ammonium purpurate, with the CAS registry number 3051-09-0 and EINECS registry number 221-266-6, has the IUPAC name of Ammonium 2,6-dioxo-5-[(2,4,6-trioxo-5-hexahydropyrimidinylidene)amino]-3H-pyrimidin-4-olate. It is also known as Murexide, and it is the ammonium salt of purpuric acid. It is a kind of reddish purple powder in its dry state, and slightly soluble in water. The molecular formula of this chemical is C₈H₈O₆N₆.

Preparation of Ammonium purpurate: It can be prepared by heating alloxantin in ammonia gas to 100°C, or by boiling uramil (5-aminobarbituric acid) with mercury oxide.

Uses of Ammonium purpurate: Its color purpurate ranges from yellow in strong acidic pH through reddish-purple in weakly acidic solutions to blue-purple in alkaline solutions. Because of this property, it is used as 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. And it is also used as a colorimetric reagent for measurement of calcium and rare earth metals.
