GALLOCYANINE Usage And Synthesis

Chemical Properties

black powder

Uses

Gallocyanine is used as an intermediate in chemical research. It is a small molecule dye that also inhibits DKK1 of the Wnt pathway.

Uses

As a dye; in alkali carbonate solution as a reagent for lead with which it forms a deep violet color.

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+).

Preparation

excessive amounts of ?N,N-dimethyl-4-nitrosobenzenamine and??3,4,5-Trihydroxybenzoic acid in methanol reaction (incomplete reaction in ethanol).

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.

Properties and Applications

red light navy blue. Insoluble in water, slightly soluble in ethanol for blue purple. In concentrated sulfuric acid for Daisy blue, dilution after magenta. Dye aqueous solution to join sodium hydroxide as red light purple.
