METHYL GREEN Usage And Synthesis

Definition

ChEBI: Methyl green is 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. It has a role as a fluorochrome and a histological dye. It is an organic chloride salt, an iminium salt and a quaternary ammonium salt. It contains a methyl green(2+).
