Definition

ChEBI: Gallocyanin is an organic chloride salt composed of 1-carboxy-7-(dimethylamino)-3,4-dihydroxyphenoxazin-5-ium and chloride ions in a 1:1 ratio. A histological dye used in solution with an iron alum mordant as a hematoxylin substitute in the H&E stain. It has a role as a fluorochrome and a histological dye. It contains a gallocyanin(1+).

General Description

Gallocyanine belongs to the oxazine class of dyes. It is synthesised from methanol solution of gallic acid in the presence of excess iodine. Gallocyanine is used to stain animal cells, mostly the nucleic acids. It also acts as a chelating agent and is used to determine bioactive compounds and several metal ions.
