EOSIN Usage And Synthesis
Chemical Propertiesbrownish-red powder
UsesEosin is most often used as a counterstain to haematoxylin in H&E (haematoxylin and eosin) staining. H&E staining is one of the most commonly used techniques in histology.
UsesAnti Septic
DefinitionChEBI: An organic sodium salt that is 2',4',5',7'-tetrabromofluorescein in which the carboxy group and the phenolic hydroxy group have been deprotonated and the resulting charge is neutralised by two sodium ions.
Preparationcountries called red. Fluorescent element (C.I. Acid Yellow 73, C.I. 45350) in water or ethanol solution bromine into four bromine derivatives, and then into sodium salt.
Safety ProfilePoison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits very toxic fumes of Brand NazO. See also BROMIDES.
Properties and Applicationsyellow peach. Orange powder, soluble in water and ethanol with fluorescent blue light is yellowish red solution. Meet strong sulfuric acid yellow, it will be diluted yellow light red precipitate generated. Dyeing copper ions in the blue colour and lustre; Iron ion colour and lustre in the dark blue. Discharge the gender is good. Mainly used in red ink and red pencils, only comfortable carpet dyeing. After refining can be used as medicine and cosmetics of coloring. Can also be used in leather dyeing. The aluminum salt can be used as organic pigments.

Purification MethodsDissolve it in the minimum volume of H2O (1g/mL), filter and add EtOH until separation of salt is complete. Filter the solid off, wash it with absolute EtOH, then Et2O and dry it first in air, then at 100o. It is used for staining blood cells and for estimating traces of Ag.
