EOSIN Chemical Properties,Usage,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.
  • Uses Anti Septic
  • 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.
  • 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.
  • 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.
  • Properties and Applications yellow 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 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.
