EOSIN Chemical Properties,Uses,Production
Chemical Properties
brownish-red powder
Uses
Eosin 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.
Preparation
countries 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.
Definition
ChEBI: 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.
Safety Profile
Poison 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.
Purification Methods
Dissolve 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.
