What is Murexide?
Chemical properties
Bordeaux powder
The Uses of Murexide
Murexide is used as a complexometric indicator in analytical chemistry for complexometric titrations of calcium, copper nickel and cobalt. It is an inhibitor of dihydrofolate reductase. Further, it acts as an enhancer of sonochemical destruction of chlorinated hydrocarbon pollutants.
The Uses of Murexide
Indicator for complexometric titrations.
What are the applications of Application
Murexide is a dye that passes the test for complexometric indicator
Purification Methods
The sample may be grossly contaminated with uramil, alloxanthine, etc., and may be difficult to purify. It is better to synthesise it from pure alloxanthine [Davidson J Am Chem Soc 58 1821 1936]. Recrystallise it from water. [Kuhn & Lyman Chem Ber 69 1547 1936, Beilstein 25 I 709, 25 III/IV 4236.]
