ERYTHROSIN B Usage And Synthesis
DescriptionFD & C Red No. 3 is principally the disodium salt of the monohydrate of 9(ocarboxyphenyl)-6-hydroxy-2,4,5,7-tetraiodo-3H- xanthen-3-one.
The colorant is a brown powder that dissolves in water to give a solution red at neutrality, with a yellow-brown precipitate in acid, and with a red precipitate in base. When dissolved in concentrated sulfuric acid, it yields a brown-yellow solution that evolves iodine and a precipitate of the free acid when heated.
FD & C Red No. 3 is used in dietary supplements, confectionery products, dairy products, cherries, jellies, jams, dessert powders, canned fruit and vegetable products, fish products, condiment sauces and bakery goods.1 .
Chemical Propertiesred to brown powder
UsesErythrosin B (FD&C Red #3) is a colorant. It is not recommended for use below ph 5.0, being insoluble at ph 3–5 but being stable at ph 7 and 8. It has a solubility in water of 9 g/100 ml at 25°c. It has fair stability to oxidation and poor to fair stability to light, while having good stability in 10% sugar systems. It has exceptional clarity and brilliance, having a bluish pink hue with very good tinctorial strength. It has poor compatibility with food components and is used in candies and confections as well as cherry dyeing. The common name is erythrosine.
UsesBiological stain; color additive.
UsesErythrosine B is a derivative of fluorone and is used as a cherry-pink synthetic colour additives used on food products.
Usesantibacterial
Preparationfluorescent element (C.I. Acid Yellow 73, C.I. 45350) or ethanol in aqueous solution of the four iodine, then into sodium salt.
DefinitionChEBI: An organic sodium salt that is the disodium salt of 2-(2,4,5,7-tetraiodo-6-oxido-3-oxo-8a,10a-dihydroxanthen-9-yl)benzoic acid.
General DescriptionErythrosin B (C.I. 45430)for microscopy Certistain?, is a dry dye for microscopy that is often used as a counterstain, vizualising proteins, connective tissues, fibers and keratin in sample material of human origin. Depending on user requirements and personal preferences, it can be used for the preparation of the commonly used aqueous or alcoholic Erythrosin B staining solutions. As the dye belongs to the portfolio of Certistain? dyes, it is chemically analyzed according to strict specifications before release (CE marked and IVD product) and a high staining quality, with reliable staining results is guaranteed. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
Flammability and ExplosibilityNotclassified
Biochem/physiol ActionsErythrosin B, also called as eosin B, is a xanthene dye. It belongs to the family of fluorescein dyes. Erythrosin B is an artificial food dye that induces hyperkinesis when swallowed by susceptible children. It plays a major role in inhibiting dopamine uptake and high affinity 3H-ouabain binding and ion transport in synaptosomes from rat caudate nucleus.
Properties and Applicationsblue light pink. Soluble in water is cherry red, no fluorescence. The strong sulfuric acid is palm in light yellow, diluted into palm yellow light precipitation. In water solution to join sodium hydroxide to create soluble red precipitate.
