| Hazard Information | Back Directory | [Definition]
ChEBI: An iminium salt composed of (4-{[4-(dimethylamino)phenyl][4-(trimethylazaniumyl)phenyl]methylidene}cyclohexa-2,5-dien-1-ylidene)(dimethyl)ammonium and chloride ions in a 1:2 ratio. A histological dye used to demonstrate nucleic acids by the Unna-Pappenheim
stain, in conjunction with Pyronin Y. | [Description]
Methyl Green is a DNA stain used as a tracking dye in acid buffers for electrophoresis. It helps differentiate bacteria and is also a tissue stain for nucleoli and mitochondria in tissues. It is used with Bismarck Brown frequently. | [Chemical Properties]
Methyl green is a metallic green microcrystal or bright green powder. It is soluble in water and appears bluish-green. As a basic dye, it readily binds to highly polymerized DNA, producing a green color. It is also known as Double Green SF. It appears as green crystals with a golden luster or as a light green powder. It is soluble in water and appears bluish-green. It is slightly soluble in ethanol but insoluble in ether or amyl alcohol.
Methyl green exists in two forms. Formula I: Molecular formula C26H33Cl2N3. Molecular weight 458.49. It appears as green crystals with a golden luster or as a light green powder. It is soluble in water, slightly soluble in ethanol, and insoluble in ether. It is typically a complex salt of zinc chloride. Formula II: Molecular formula: C27H35BrClN3. Molecular weight: 516.98. Green powder, soluble in water, exhibits a greenish-blue color. The solution is yellow at pH 0.2 and blue at pH 1.8. | [Uses]
Methyl Green powder dye is used in various staining methods in microscopy. It is also used with Pyronine Y dye for one stage DNA (green) and RNA (red) staining method. It is also used as a counterstain with other reactions, such as demonstration of enzymatic activity and for mitochondrial staining according to Altmann. Methyl green solution is a suitable counterstain for chloroacetate esterase, nonspecific esterase, alkaline phosphatase, peroxidase, naphthol AS acetate esterase, and acid phosphatase. | [Preparation]
chlorine methane and (C.I.Basic Violet 1, C.I. 42535) reaction | [Properties and Applications]
green light blue. Soluble in water for blue light green, not soluble in ethanol and e alcohol. The strong sulfuric acid to red light yellow, yellow green for diluted. Dyes to join sodium hydroxide solution to colorless.
