16423-68-0 Usage

Description

FD & 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 .

Definition

ChEBI: 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 Description

Erythrosin 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.

For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.

Flammability and Explosibility

Notclassified

Biochem/physiol Actions

Erythrosin 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.

Check Digit Verification of cas no

The CAS Registry Mumber 16423-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,2 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16423-68:
(7*1)+(6*6)+(5*4)+(4*2)+(3*3)+(2*6)+(1*8)=100
100 % 10 = 0
So 16423-68-0 is a valid CAS Registry Number.

Technique for preparing erythrosin B

-

Paragraph 0048; 0051; 0052; 0053; 0054, (2017/04/19)

The invention discloses a technique for preparing erythrosin B. The technique comprises the steps of 1, making fluorescein which serves as the start material react with iodate to generate erythrosine under the action of a solvent and a catalyst; 2, making the erythrosine prepared in step 1 react with alkali to generate the erythrosine B under the action of a solvent. The technique has the advantages that operation is easy, cost is low, yield is high, pollution is light, and iodine utilization rate is high. The technique is suitable for industrial production and is suitable for production of most relevant enterprises.
