ETHYL EOSIN Usage And Synthesis
Chemical Propertiesred to brown powder
UsesEthyl eosin is a histological stain that has been used in the Stoval and Black method for illustrating Negri bodies in the central nervous system of rabid animals. Dyes and metabolites.
DefinitionChEBI: An organic potassium salt having 2,4,5,7-tetrabromo-9-{2-[(ethyloxy)carbonyl]phenyl}-3-oxo-3H-xanthen-6-olate as the counterion.
PreparationFluorescein (C.I. Acid Yellow 73, C.I. 45350) in water or ethanol solution bromide into four bromine derivatives, and then into sodium salt, then product (C.I. Acid Red 87) ethyl ester and translated into potassium.
Properties and Applicationsbrilliant blue light red. Slightly soluble in hot water for cherry red, with weak green yellow fluorescence, slightly soluble in ethanol to red, with brown light yellow fluorescence. In concentrated sulfuric acid to yellow, dilution after brown light yellow precipitation.
