Description

Description générale

Murexide is the ammonium salt of purpuric acid that appears as a slightly reddish-purple powder and is soluble in water. It is mainly used as an indicator for complexometric titrations to measure water hardness and as a colorant/pigment in the dye industry.

Application

Murexide is used for the histochemical staining of calcium in the skeleton. It is suitable for staining the hemijaws for dental caries scoring.
