white to light brown, light green or light blue | [Uses]
A metabolite of Malachite Green | [Uses]
For directly dyeing silk, wool, jute and leather; dyeing cotton after mordanting. Biological stain. Clinical reagent (inorganic phosphate assay). As spot test reagent for detecting sulfurous acid and cerium. As acid-base indicator: pH 0.0 yellow, 2.0 green; 11.6 green, 14 colorless. | [Definition]
ChEBI:Leucomalachite green is a benzenoid aromatic compound. | [Biological Activity]
Leucomalachite green (LMG) is a chief metabolite of malachite greena triphenylmethane dye th at has been used generally as an antifungal drug in the fish industry. DNA adducts formed in livers of rats fed with leucomalachite green have been observed with little mutagenic or carcinogenic effect. LMG is one of the most commonly used reagents for presumptive blood test. It gives a characteristic green color in the presence of blood. LMG destroys DNA in the bloodthereforethe chances of DNA recovery and amplification is reduced or eliminated. | [Purification Methods]
Crystallise it from 95% EtOH (10mL/g), then from *benzene/EtOH, and finally from pet ether. [Beilstein 13 H 275, 13 II 89, 13 II 135, 13 III 529, 13 481.] |
