Description

Ethyl green is an iminium salt composed of [4-([4-(dimethylamino)phenyl]{4-[ethyl(dimethyl)azaniumyl]phenyl}methylidene)cyclohexa-2,5-dien-1-ylidene](dimethyl)ammonium, bromide and chloride ions in a 1:1:1 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, a quaternary ammonium salt, an iminium salt and an organic bromide salt. It contains an ethyl green(1+).
