Introduction
It is also known as "purple", "methyl violet", "gentian violet." It belongs to triphenylmethane type alkaline dyes. Scientific name:"hexamethyl chloride rose aniline." It appears as dark green powder with metallic luster. It is soluble in water, alcohol and chloroform, but insoluble in ether. Its solubility in water is 1.68% and its solubility in 95% ethanol is 13.87%. However, the solubility of its iodide in two solvents is only 0.035% and 1.78% respectively. Both its aqueous solution and alcohol solution are purple.
